The severity of the clinical phenotype did not correspond to that expected of a frameshift mutation. A small amount of functional factor VIII protein was detected in the patient's plasma. Analysis of DNA and RNA molecules from normal and affected individuals and in vitro transcription/translation suggested a partial correction of the molecular defect, because of the following: (i) DNA replication/RNA transcription errors resulted in restoration of the reading frame and/or (ii) 'ribosomal frameshifting' resulted in the production of normal factor VIII polypeptide and, thus, in a milder-than-expected hemophilia A.

(1988)</a> demonstrated the usefulness of DNA amplification followed by direct nucleotide sequencing in the search for mutations in X-linked disorders because of the unambiguous sequencing data obtained when the amplified DNA is from a male patient. In a 17-year-old Greek male with moderately severe hemophilia A (<a href="/entry/306700">306700</a>) (JH20), they detected a mutation by analysis of genomic DNA with TaqI; contrary to previous experience, the mutation was not a C-to-T or G-to-A transition. (The unifying mechanism of these mutations is thought to be methylation-induced C-to-T transitions at CpG dinucleotides involving either the coding or the complementary strand of DNA; see <a href="#20" class="mim-tip-reference" title="Bird, A.

In this case the point mutation was in exon 7, where codon 291 for glutamate (GAA) was changed to one for glycine (GGA), leading to a change in amino acid 272 of the mature factor VIII protein. The mutation had arisen de novo in a germ cell of the patient's mother. The patient had 2% factor VIII activity, 3.5% factor VIII antigen, and moderate hemophilia A. <a href="https://pubmed.ncbi.nlm.nih.gov/?term=2833855+6253938" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p>

By expression in baby hamster kidney cells, they found that F8 with the N1922S mutation (F8-N1922S) was weakly secreted compared with wildtype F8, although secreted F8-N1922S showed normal or near-normal activity. Wildtype F8 followed the classic secretory pathway; however, F8-N1922S was delayed in the endoplasmic reticulum (ER), prior to processing and packaging in the Golgi. Use of conformation-specific monoclonal antibodies revealed that the delay in the ER was due to a defect in folding of the A3 domain and the adjacent C1 domain. <a href="#125" class="mim-tip-reference" title="Summers, R.

Both of her parents had normal values of factor VIII activity, and von Willebrand disease was excluded. Karyotype analysis demonstrated no obvious alteration, and no F8 gene inversions were found. Direct sequencing of the F8 gene exons revealed a frameshift-stop mutation (Q565delC/ter566) in the heterozygous state in the proposita only. F8 gene polymorphism analysis indicated that the mutation must have occurred de novo in the paternal germline. Furthermore, analysis of the pattern of X chromosome methylation at the human androgen receptor gene locus demonstrated a skewed inactivation of the derived maternal X chromosome from the lymphocytes of the proband's DNA. Thus, the severe hemophilia A in the proposita resulted from a de novo F8 gene mutation on the paternally derived X chromosome, associated with a nonrandom pattern of inactivation of the maternally derived X chromosome. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=11110718" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p>

The mutation was not present in the twins' healthy sister or parents, suggesting that it had occurred de novo in the germline of 1 parent. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=12351418" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p>

(2018)</a> identified an intronic deletion (c.2113+461_2113+473del, NM_000132.3) in intron 13 of the F8 gene. Transcription analysis of patient cells showed an aberrant transcript resulting from this deletion; it caused the insertion of a 122-bp intronic fragment (c.2113_2114ins2113+477_2113+598) at the exon 13-14 junction. This out-of-frame insertion was predicted to result in a truncated protein (Gly705AspfsTer37). DNA sequencing analysis showed that the included pseudoexon corresponds to an antisense AluY element, and that the deletion removed a part of the poly(T)-tail from the right arm of AluY. The findings suggested aberrant exonization of the AluY element that likely resulted from decreased binding of the cryptic exon silencer HNRNPC (<a href="/entry/164020">164020</a>). Disruption of or siRNA-mediated knockdown of HNRNPC in HeLa cells reproduced the effect of the deletion. Screening of 992 unrelated French families with mild hemophilia A found a deletion in the poly(T)-tail of AluY in intron 13 in 6.1% of families, although these resulted from several different intronic deletions in this region, suggesting a recurring molecular mechanism. Haplotype analysis suggested a founder effect for c.2113+461_2113+473del. The patients also carried a normal F8 transcript in addition to the aberrant transcript, explaining the mild phenotype. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=29357978" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p>

<span class="mim-text-font">
<p>The F8 gene encodes coagulation factor VIII, a large plasma glycoprotein that functions in the blood coagulation cascade as a cofactor for the factor IXa (300746)-dependent activation of factor X (F10; 613872). Factor VIII is activated proteolytically by a variety of coagulation enzymes, including thrombin (F2; 176930). Factor VIII is tightly associated in the blood with von Willebrand factor (VWF; 613160), which serves as a protective carrier protein for factor VIII (summary by Toole et al., 1984; review by Hoyer, 1994). </p>

<strong>Cloning and Expression</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>Fay et al. (1982) isolated a highly purified human factor VIII that consisted of a single high molecular weight polypeptide chain having the highest specific activity. </p><p>Toole et al. (1984) isolated clones corresponding to the F8 gene from a human cDNA library. Independently and simultaneously, Gitschier et al. (1984) and Wood et al. (1984) also cloned and expressed the F8 gene. The deduced precursor protein has 2,351 amino acids and a molecular mass of 267 kD. The leader sequence of the proprotein contains 19 amino acids, yielding a mature protein of 2,332 amino acids. The protein has an obvious domain structure, contains sequence repeats, and is structurally related to factor V (F5; 612309) and ceruloplasmin (CP; 117700). F8 has 3 copies of an A domain of 330 to 380 amino acids, a B domain of about 925 amino acids, and 2 C domains of about 160 amino acids. The domains are arranged A1-A2-B-A3-C1-C2. Both A and C repeats show conservation of cysteines, and the B region contains most potential N-glycosylation sites. Northern blot analysis detected a 9-kb F8 transcript. </p><p>The F8 gene is expressed in human liver, spleen, lymph nodes, and a variety of other tissues, but not in bone marrow, peripheral blood lymphocytes, or endothelial cells (Wion et al., 1985). </p>

<strong>Gene Structure</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>The F8 gene contains 26 exons and spans 186 kb (Gitschier et al., 1984). </p><p>Levinson et al. (1990) found a curious example of a gene within a gene. In looking for transcripts from the Xq28 region, they found one referred to as the A gene that hybridized to a region in exon 22 of the F8 gene. The A or F8A gene (305423) was in reverse orientation to F8 and was contained entirely in intron 22. Computer analysis of the sequence suggested that the A gene encodes a protein, with the complication that codon usage analysis suggested a frameshift halfway through the gene. The A gene cDNA also bound to mouse, monkey, and rat genomic DNA in a 'zoo blot.' The mouse A gene was also found to be on the X chromosome but not within the mouse F8 gene as it is in the human. </p><p>Freije and Schlessinger (1992) demonstrated that the X chromosome contains 3 copies of F8A and its adjacent regions, 1 in intron 22 and 2 telomeric and upstream to the F8 gene transcription start site. Gene F8A, which is transcribed in the opposite direction to F8, is intronless and completely nested within intron 22. Approximately 500 kb upstream of the F8 gene, there are 2 additional transcribed copies of the F8A gene. Lakich et al. (1993) pointed out that intron 22 is unusual in many respects. At 32 kb, it is the largest intron in the F8 gene. It also contains a CpG island, located about 10 kb downstream of exon 22. This island appears to serve as a bidirectional promoter for the F8A and F8B (305424) genes. The F8B gene is also located in intron 22 and is transcribed in the opposite direction from F8A; its first exon lies within intron 22 and is spliced to exons 23-26. The F8A and B genes are both expressed ubiquitously. </p><p>Having previously reported the existence of 5 CpG islands close to the F8 gene, 4 of which they cloned by genomic walking, Gitschier's group (Kenwrick et al., 1992) reported the isolation of the remaining island, located approximately 70 kb telomeric of the 5-prime end of the F8 gene. They identified cDNA clones corresponding to 2 transcribed sequences, C6.1A (BRCC3; 300617) and C6.1B (MTCP1; 300116), that originate from this CpG island. The C6.1A gene was highly conserved between species and expressed abundantly in many human and mouse tissues. No striking homologies to existing genes could be found for either sequence. Kenwrick et al. (1992) found that both genes were deleted in 2 brothers who suffered from mental handicap and dysmorphism as well as hemophilia A (306700). </p>

<strong>Mapping</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>By in situ hybridization, Tantravahi et al. (1986) concluded that the F8 gene is located in the proximal part of chromosome Xq28 with probes DX13 and St14 distally located. Using a hybrid cell line that contains only a terminal Xq28 fragment, Tantravahi et al. (1986) found that F8 probes did not hybridize but the DX13 and St14 did hybridize to the DNA of that cell line. </p><p>Patterson et al. (1987) showed that the G6PD (305900) and F8 genes lie within 500 kb of each other. Arveiler et al. (1989) showed that G6PD and F8 are in the same 290-kb pulsed field gel electrophoresis fragment, but did not establish which of the genes is more proximal. </p><p>Kenwrick and Gitschier (1989) established the order: cen--R/GCP--GDX--G6PD--F8--DXS15--tel. The direction of transcription of the GDX, G6PD, and F8 genes is toward the centromere, i.e., the R/GCP end of the region. Patterson et al. (1989) showed that the genomic sequences recognized by the anonymous probe 767 (DXS115) are localized to 2 sites within Xq28. One site lies within intron 22 of the F8 gene. The second site, which contains the RFLPs detected by 767, is located within 1.2 megabases of the F8 gene. Genetic data indicate tight linkage of F8 and DXS115; maximum lod = 8.30 at theta = 0.04. </p><p>G6PD (305900) is one of the 5 rather tightly linked loci located on Xq28, the others being CBD (303800), CBP (303900), HEMA, and ALD (300371). In a physical map of the most distal 12 Mb of Xq, Poustka et al. (1991) found that the F8 gene lies about 1.1 Mb from the telomere, with G6PD proximal to it, and about 1.5 Mb from the telomere. This contradicted the earlier impression that the gene is located in the proximal part of Xq28. </p><p>In a 9-year-old Malaysian female with de novo hemophilia A (306700) as well as a complex de novo translocation involving one X chromosome and one chromosome 17 (Muneer et al., 1986), Migeon et al. (1993) identified a breakpoint within Xq28 with deletion of the 5-prime end of the factor VIII gene, leaving the more proximal G6PD locus intact on the derivative chromosome 17. As the deleted segment included the 5-prime half of F8C as well as the subtelomeric DXYS64 locus, they concluded that F8 is oriented on the chromosome with its 5-prime region closest to the telomere. </p>

<p>Ratnoff and Bennett (1973) reviewed the genetics of hereditary disorders of blood coagulation. </p><p><strong><em>Hemophilia A</em></strong></p><p>
Gitschier et al. (1985) identified truncating mutations in the F8 gene (see, e.g., 300841.0001-300841.0003) as the basis for hemophilia A (306700). A severe hemophiliac with no detectable factor VIIIC activity had an R2307X mutation (300841.0001). Gitschier et al. (1986) found that the same codon was converted to glutamine (R2307Q; 300841.0042) in a mild hemophiliac with 10% of normal activity. A diminished level of factor VIII Ag in the latter patient coincided with the level of clotting activity, suggesting that the abnormal factor VIII was relatively unstable. </p><p>In a study of 83 patients with hemophilia A, Youssoufian et al. (1986) identified 2 different point mutations, one in exon 18 and one in exon 22, that recurred independently in unrelated families. Each mutation produced a nonsense codon by a change of CG to TG. In the opinion of Youssoufian et al. (1986), these observations indicated that CpG dinucleotides are mutation hotspots. It had been postulated that methylated cytosines may be mutation hotspots because 5-methylcytosine can spontaneously deaminate to thymine, resulting in a C-to-T transition in DNA. </p><p>Levinson et al. (1987) used RNAse A cleavage and DNA sequencing of the altered region to identify a mutation in the F8 gene in a patient with hemophilia. The mutation was a novel G-to-C transversion which resulted in a missense mutation, with proline being substituted for arginine in one of the active domains of the factor VIII molecule. </p><p>Youssoufian et al. (1987) characterized 5 different partial deletions of the F8 gene in 83 patients with hemophilia. None had developed circulating inhibitors. One of the deletions occurred de novo in a germ cell of the maternal grandmother, while a second deletion occurred in a germ cell of a maternal grandfather. The findings indicated that de novo deletions of X-linked genes can occur in either male or female gametes. Youssoufian et al. (1988) reported 6 other partial F8 gene deletions in severe hemophilia A, bringing to 12 the number of deletions among 240 patients. No association was observed between the size or location of deletions and the presence of inhibitors to factor VIII. Furthermore, no 'hotspots' for deletion breakpoints were identified. </p><p>Youssoufian et al. (1988) screened 240 patients with hemophilia A and found CG to TG transitions in an exon in 9. They identified novel missense mutations leading to severe hemophilia A and estimated that the extent of hypermutability of CpG dinucleotides is 10 to 20 times greater than the average mutation rate for hemophilia A. </p><p>Cooper and Youssoufian (1988) collated reports of single basepair mutations within gene coding regions causing human genetic disease. They found that 35% of mutations occurred within CpG dinucleotides. Over 90% of these mutations were C-to-T or G-to-A transitions, which thus occur within coding regions at a frequency 42-times higher than that predicted from random mutation. Cooper and Youssoufian (1988) believed these findings were consistent with methylation-induced deamination of 5-methylcytosine and suggested that methylation of DNA within coding regions may contribute significantly to the incidence of human genetic disease. </p><p>Higuchi et al. (1988) found deletion of about 2,000 bases spanning exon 3 and part of IVS3 of the F8 gene in a patient with severe hemophilia A. The mother was judged to be a somatic mosaic because the defective gene could be identified in only a portion of the leukocytes and cultured fibroblasts. </p><p>By use of a cDNA probe corresponding to exons 14-26 of F8, Bardoni et al. (1988) studied 49 Italian patients with severe hemophilia A. They found no TaqI site mutations, but did find a partial deletion, eliminating exons 15-18 and spanning about 13 kb (300841.0046), in a patient with anti-factor VIII antibodies. </p><p>In a case of hemophilia A, Kazazian et al. (1988) described the first instance of insertional mutagenesis in man caused by a long inserted element (LINE) in the F8 gene. L1 (LINE-1) sequences are a human-specific family of long, interspersed, repetitive elements, present in about 100,000 copies dispersed throughout the genome. The full-length L1 sequence is 6.1 kilobases, but most L1 elements are truncated at the 5-prime end, resulting in a 5-fold higher copy number of 3-prime sequences. Kazazian et al. (1988) found insertions of L1 elements into exon 14 of the F8 gene in 2 of 240 unrelated patients with hemophilia A. Both of these insertions (3.8 and 2.3 kb, respectively) contained 3-prime portions of the L1 sequence. They interpreted these results as indicating that certain L1 sequences in man can be dispersed, presumably by an RNA intermediate, and cause disease by insertional mutation. Both of the above insertions were de novo events, appearing either during embryogenesis in the patient or in the mother's germ cells. The L1 element transposed into one of these patients was demonstrated by Dombroski et al. (1991) to have come from a retrotransposable element located on chromosome 22 (see 151626). </p><p>Woods-Samuels et al. (1989) characterized a third L1 insertion in intron 10 of the F8 gene of a hemophilia A patient. This L1 insertion was not a cause of hemophilia in the patient because it was also present in the maternal grandfather, who did not have the disease. Altogether the L1 insertion was present in 4 generations of the family. All 3 of the L1 insertions discovered by Dombroski et al. (1991) have open reading frames (ORFs), and the 3 derived amino acid sequences are 98 to 99% identical. They show similarity in the sequence of the L1 3-prime ORFs, and the polymerase domain of reverse transcriptase was observed in all 3 L1 insertions. The presence of ORFs and the close sequence similarity of these recently inserted L1 elements provide indirect evidence for the existence of a set of functional L1 elements that encodes 1 or more proteins necessary for their retrotransposition. </p><p>In studies of 83 unrelated Finnish patients with hemophilia A, Levinson et al. (1990) identified specific mutations, falling into 3 classes, in 10 patients: 5 mutations caused loss of TaqI restriction sites; 1 point mutation resulted in a new TaqI site; and 4 represented partial gene deletions. Although exons 5 and 6 were involved in 3 of the 4 partial gene deletions, the extent of the DNA loss differed in each. The fourth deletion was located entirely within intron 1. There was no history of hemophilia in 8 of the 10 families. The origin of the mutation was determined in 6 of these pedigrees, 2 of which showed evidence for maternal mosaicism. </p><p>Brocker-Vriends et al. (1990) described a case of hemophilia A due to partial deletion of the F8 gene of about 2 kb, spanning exon 5 and part of introns 4 and 5; the mother was a somatic and presumably gonadal mosaic for the mutation although coagulation assays and RFLP analysis in the family did not suggest a carrier status. </p><p>McGinniss et al. (1993) reported that half of hemophilia A patients have no detectable factor VIII; about 5% have normal levels of dysfunctional factor VIII as protein and are termed CRM-+, whereas the rest ( 45%) have plasma factor VIII Ag protein reduced to an extent roughly comparable to the level of factor VIIIC activity and are designated CRM-reduced. They found in an analysis of mutations that almost all CRM-positive/reduced mutations (24/26) were missense, and many (12/26) occurred at CpG dinucleotides. They showed that 18 of 19 amino acid residues altered by mutation in these patients were conserved in the porcine and murine sequences. Almost half of the mutations (11/26) were clustered in the A2 domain. </p><p>In a review, Antonarakis et al. (1995) collected the findings of more than 1,000 hemophilia subjects examined for F8 gene mutations. These include point mutations, inversions, deletions, and unidentified mutations which constitute 46%, 42%, 8%, 4%, and 91%, 0%, 0%, and 9%, respectively, of those with severe versus mild to moderate disease, respectively, in selected studies. The 266 point mutations described as of April, 1994 comprised missense (53%), CpG-to-TpG (16%), small deletions (12%), nonsense (9%), small inversions and splicing (3% each), and missense polymorphisms and silent mutations in exons (2% each). In addition to these point mutations 100 different larger deletions and 9 insertion mutations had been reported. </p><p>In a study of 147 sporadic cases of severe hemophilia A, Becker et al. (1996) were able to identify the causative defect in the F8 gene in 126 patients (85.7%). An inversion of the gene was found in 55 patients (37.4%), a point mutation in 47 (32%), a small deletion in 14 (9.5%), a large deletion in 8 (5.4%), and a small insertion in 2 (1.4%). In 4 (2.7%), mutations were localized but not yet sequenced. No mutation was identified in 17 patients (11.6%). The identified mutations occurred in the B domain in 16 (10.9%); 4 of these were located in an adenosine nucleotide stretch at codon 1192, indicating a mutation hotspot. Somatic mosaicism was detected in 3 (3.9%) of 76 patients' mothers, comprising 3 of 16 de novo mutations in the patients' mothers. Investigation of family relatives allowed detection of a de novo mutation in 16 of 76 2-generation and 28 of 34 3-generation families. On the basis of these data, Becker et al. (1996) estimated the male:female ratio of mutation frequencies (k) to be 3.6. By use of the quotients of mutation origin in maternal grandfather to patients' mother or to maternal grandmother, k values were directly estimated as 15 and 7.5, respectively. Considering each mutation type separately, they found a mutation type-specific sex ratio of mutation frequencies. Point mutations showed a 5-to-10-fold-higher and inversions a more than 10-fold-higher mutation rate in male germ cells, whereas deletions showed a more than 5-fold-higher mutation rate in female germ cells. Consequently, and in accordance with the data of other disorders such as Duchenne muscular dystrophy, the results indicated to Becker et al. (1996) that at least for X-chromosomal disorders the male:female mutation rate is determined by its proportion of the different mutation types. </p><p>The molecular diagnosis of hemophilia A is challenging because of the high number of different causative mutations that are distributed through the large F8 gene. The putative role of the novel mutations, especially missense mutations, may be difficult to interpret as causing hemophilia A. Guillet et al. (2006) identified 95 novel mutations out of 180 different mutations found among 515 patients with hemophilia A from 406 unrelated families followed up at a single hemophilia treatment center in a Paris hospital. The 95 novel mutations comprised 55 missense mutations, 12 nonsense mutations, 11 splice site mutations, and 17 small insertions/deletions. They used a strategy in interpreting the causality of novel F8 mutations based on a combination of the familial segregation of the mutation, the resulting biologic and clinical hemophilia A phenotype, and the molecular consequences of the amino acid substitution. For the latter, they studied the putative biochemical modifications: its conservation status with cross-species factor VIII and homologous proteins, its putative location in known factor VIII functional regions, and its spatial position in the available factor VIII 3D structures. </p><p>Among 1,410 Italian patients with hemophilia A, Santacroce et al. (2008) identified 382 different mutations in the F8 gene, 217 (57%) of which had not previously been reported. Mutations leading to a null allele accounted for 82%, 15%, and less than 1% of severe, moderate, or mild hemophilia, respectively. Missense mutations were identified in 16%, 68%, and 81% of severe, moderate, or mild hemophilia, respectively, yielding a good genotype/phenotype correlation useful for treatment and genetic counseling. </p><p>To establish a national database of F8 mutations, Green et al. (2008) identified and cataloged multiple mutations in approximately one-third of the U.K. hemophilia A population. The risk of developing inhibitors for patients with nonsense mutations was greater when the stop codon was in the 3-prime half of the mRNA. The most common change was the intron 22 inversion (300841.0067), which accounted for 16.6% of all mutations and for 38% of those causing severe disease. </p><p><strong><em>Inversion Mutations in Intron 22 of the F8 Gene</em></strong></p><p>
Intron 22 of the human F8 gene is hypomethylated on the active X and methylated on the inactive X. Inaba et al. (1990) described an MspI RFLP in intron 22 of the F8 gene. Japanese showed 45% heterozygosity and Asian Indians showed 13%; polymorphism was not found in American blacks or Caucasians. </p><p>Naylor et al. (1992) found an unusual cluster of mutations involving regions of intron 22 not examined earlier and leading to defective joining of exons 22 and 23 in the mRNA (300841.0067) as the cause of hemophilia A in 10 of 24 severely affected UK patients. These results confirmed predictions about the efficacy of the mRNA-based method suggested by Naylor et al. (1991), and also excluded hypotheses proposing that mutations outside the F8 gene are responsible for a large proportion of severe hemophilia A. </p><p>Of the 28 patients reported by Naylor et al. (1993), 5 had mild or moderate disease and all had a missense mutation. The other 23 patients were severely affected; unexpectedly, intron 22 seemed to be the target of approximately 40% of the mutations causing severe hemophilia A. Naylor et al. (1993) found that the basis of the unique F8 mRNA defect that prevented PCR amplification across the boundary between exons 22 and 23 was an abnormality in the internal regions of intron 22. They showed that exons 1-22 of the F8 mRNA had become part of a hybrid message containing new multiexonic sequences expressed in normal cells. The novel sequences were not located in a YAC containing the whole F8 gene. Southern blots from patients probed by novel sequences and clones covering intron 22 showed no obvious abnormalities. Naylor et al. (1993) also suggested that inversions involving intron 22 repeated sequences are the basis of the mRNA defect. These mutations in severely affected patients occur at the surprising rate of approximately 4 x 10(-6) per gene per gamete per generation. Furthermore, it has been shown that these de novo inversions occur more frequently in males than females with a ratio of 302:1 estimated in male:female germ cells. </p><p>The F8A gene (305423) is contained entirely within intron 22 of the F8 gene and is transcript in the reverse orientation from the F8 gene (Levinson et al., 1990). Lakich et al. (1993) proposed that many of the previously unidentified mutations resulting in severe hemophilia A are based on recombination between the homologous F8A sequences within intron 22 and upstream of the F8 gene. Such a recombination would lead to an inversion of all intervening DNA and a disruption of the gene. Lakich et al. (1993) presented evidence to support this model and described a Southern blot assay that detects the inversion. They suggested that this assay should permit genetic prediction of hemophilia A in approximately 45% of families with severe disease. </p><p>Rossiter et al. (1994) hypothesized that pairing of Xq with its homolog inhibits the intrachromosomal inversion that is responsible for nearly half of all cases of severe hemophilia A. This would predict that the event originates predominantly in male germ cells. They presented findings supporting the hypothesis: in all 20 informative cases in which the inversion originated in a maternal grandparent, DNA polymorphism analysis determined that it occurred in the male germline. In addition, all but 1 of 50 mothers of sporadic cases due to an inversion were carriers. </p><p>Inversion mutations resulting from recombinations between DNA sequences in the A gene in intron 22 of the F8 gene and 1 of 2 other A genes upstream to F8 have been shown to cause a large portion of cases. From data on more than 2,000 samples, Antonarakis et al. (1995) concluded that the common inversion mutations are found in 42% of all severe hemophilia A subjects. Whereas 98% of the mothers of those with inversions were carriers of the inversion, only about 1 de novo inversion was found in maternal cells for every 25 mothers of sporadic cases. When the maternal grandparental origin of inversions was examined the ratio of de novo occurrences in male:female germ cells was 69:1. </p><p>Brinke et al. (1996) reported the presence of a novel inversion in 2 hemophilic monozygotic twins. These patients showed an inversion that affects the first intron of the F8 gene, displacing the most telomeric exon (exon 1) of F8 further towards the telomere and close to the C6.1A gene (BRCC3; 300617). Brinke et al. (1996) noted that this novel inversion creates 2 hybrid transcription units. One of these is formed by the promoter and first exon of F8 and widely expressed sequences that map telomeric to the C6.1A sequence. The other hybrid transcription unit contains the CpG island and all of the known sequence of C6.1A and the 3-prime section of most of the F8 gene. </p><p>It is hypothesized that the inversion mutations occur almost exclusively in germ cells during meiotic cell division by an intrachromosomal recombination between a 9.6-kb sequence within intron 22 and 1 of 2 almost identical copies located about 300 kb distal to the F8 gene at the telomeric end of the X chromosome. Most inversion mutations originate in male germ cells, where the lack of bivalent formation may facilitate flipping of the telomeric end of the single X chromosome. Oldenburg et al. (2000) reported the first instance of intron 22 inversion presenting as somatic mosaicism in a female, affecting only about 50% of lymphocyte and fibroblast cells of the proposita. Supposing a postzygotic de novo mutation as the usual cause of somatic mosaicism, the finding implies that the intron 22 inversion mutation is not restricted to meiotic cell divisions but can also occur during mitotic cell divisions, either in germ cell precursors or in somatic cells. </p><p><strong><em>Hemophilia A with Inhibitors</em></strong></p><p>
Approximately 10 to 20% of patients with severe hemophilia A develop antibodies, known as inhibitors, to factor VIII following treatment with exogenous factor VIII. Most of these patients have nonsense mutations or deletions in the F8 gene (Antonarakis et al., 1995). </p><p>Antonarakis et al. (1985) identified several molecular defects in families with hemophilia A. One family had a deletion of about 80 kb in the F8 gene, whereas another had a single nucleotide change in the coding region of the gene, resulting in a nonsense codon and premature termination. In addition, they used 2 common polymorphic sites in the F8 gene to differentiate the normal gene from the defective gene in 4 of 6 obligate carriers from families with patients in whom inhibitors did not develop. In both the family with a large deletion and the family with premature termination, affected persons developed inhibitors. </p><p>A variety of F8 gene mutations have been found in patients with hemophilia A due to inhibitors. Among 30 such cases, Antonarakis et al. (1995) found that 87 and 13% had different nonsense and missense mutations, respectively. F8 gene inversions do not seem to be a major predisposing factor for the development of inhibitors. Among severe hemophilia A cases, 16% of those without inversions and 20% of those with inversions developed inhibitors. </p><p>Schwaab et al. (1995) found that the probability of developing factor VIII inhibitors is greater in patients with large deletions in the F8 gene. </p><p>Viel et al. (2009) sequenced the F8 gene in 78 black patients with hemophilia to identify the causative mutations and background haplotypes, which the authors designated H1 to H5. They found that 24% of the patients had an H3 or H4 haplotype, and that the prevalence of inhibitors was higher among patients with either of those haplotypes than among patients with haplotypes H1 or H2 (odds ratio, 3.6; p = 0.04), despite a similar spectrum of hemophilic mutations and degree of severity of illness in the 2 subgroups. Noting that Caucasians carry only the H1 or H2 haplotypes and that most blood donors are Caucasian, Viel et al. (2009) suggested that mismatched factor VIII replacement therapy might be a risk factor for the development of anti-factor VIII alloantibodies. </p><p><strong><em>Thrombophilia, X-Linked, due to Factor VIII Defect</em></strong></p><p>
Shen et al. (2013) evaluated F8 activity and F8 gene copy number in 179 patients with venous thromboembolism and 176 healthy controls. Patients with venous thromboembolism had significantly higher F8 activity compared to controls and also had a significantly greater number of copies of the F8 gene. F8 activity was also correlated to F8 gene copy number in patients versus controls, although this was not true for every individual patient. The F8 copy number was significantly higher in males compared to females. </p><p>In 7 individuals from 2 Italian families with thrombophilia (THPH13; 301071), Simioni et al. (2021) identified a tandem duplication in the factor VIII gene (300841.0272). The 2 families shared a 3-Mb haplotype, indicating a shared common ancestor. F8 mRNA was increased in patient lymphocytes. Increased transcriptional activity of fragments of the duplicated region was demonstrated by luciferase assay and was highest in a region (region C) that overlapped a major DNase I hypersensitivity cluster. </p>

<strong>Genotype/Phenotype Correlations</strong>

<span class="mim-text-font">
<p>In a Japanese family with mild to moderately severe hemophilia A, Young et al. (1997) found a deletion of a single nucleotide T within an A(8)TA(2) sequence of exon 14 of the F8 gene. The severity of the clinical phenotype did not correspond to that expected of a frameshift mutation. A small amount of functional factor VIII protein was detected in the patient's plasma. Analysis of DNA and RNA molecules from normal and affected individuals and in vitro transcription/translation suggested a partial correction of the molecular defect, because of the following: (i) DNA replication/RNA transcription errors resulted in restoration of the reading frame and/or (ii) 'ribosomal frameshifting' resulted in the production of normal factor VIII polypeptide and, thus, in a milder-than-expected hemophilia A. All of these mechanisms probably were promoted by the longer run of adenines, A(10) instead of A(8)TA(2), after the deleted T. Young et al. (1997) concluded that errors in the complex steps of gene expression therefore may partially correct a severe frameshift defect and ameliorate an expected severe phenotype. </p><p>Cutler et al. (2002) identified 81 mutations in the F8C gene in 96 unrelated patients, all of whom had previously typed negative for the common IVS22 inversion mutation (300841.0067). Forty-one of these mutations were not recorded in F8C gene mutation databases. Analysis of these 41 mutations with regard to location, possible cross-species conservation, and type of substitution, in correlation with the clinical severity of the disease, supported the view that the phenotypic result of a mutation in the F8C gene correlates more with the position of the amino acid change within the 3-dimensional structure of the protein than with the actual nature of the alteration. </p>

<p><strong><em>Early Mutation Detection Methods</em></strong></p><p>
Since point mutations in the F8 gene are responsible for most cases of hemophilia A and only a small proportion of these mutations could be recognized by restriction endonuclease analysis, Traystman et al. (1990) used PCR and denaturing gradient gel electrophoresis (DGGE) to characterize single nucleotide substitutions. A GC clamp was attached to the 5-prime PCR primer to allow detection of most single base changes in DNA fragments ranging in size from 249 to 356 bp. (A 'GC clamp' is a sequence rich in G and C such that it is relatively resistant to melting by heating; see Myers et al. (1985, 1985) and Abrams et al., 1990.) Ten of 11 known point mutations were definitively separated. Traystman et al. (1990) then used these methods, applied to exon 8, the 3-prime end of exon 14, exon 17, exon 18, and exon 24, in a study of 52 patients with unknown mutations. A 'new' disease-producing mutation was found in 2 of the patients: a missense mutation in exon 14 (tyr1709-to-cys and asn1922-to-asp). A previously described mutation in exon 24 (arg2209-to-gln) In addition, a new polymorphic nucleotide substitution was found in intron 7. Traystman et al. (1990) detected all of these mutations when the GC-clamped products from all 5 regions were run in the same denaturing gel. </p><p>Kogan and Gitschier (1990) likewise used DGGE to identify mutations and found a DNA polymorphism, located in intron 7, which they thought might be useful for genetic prediction in cases in which the BclI and XbaI polymorphisms are uninformative. </p><p>Higuchi et al. (1991) pointed out that whereas nearly all mutations resulting in mild to moderate hemophilia B could be detected by PCR and DGGE, these methods sufficed in only 16 of 30 (53%) patients with severe hemophilia A. They interpreted this to indicate that the mutations in DNA sequence lay outside the regions studied and may include locus-controlling regions, other sequences within introns or outside the gene that are important for its expression, or perhaps another gene involved in factor VIII expression that is very closely linked to the F8 gene. Higuchi et al. (1991) designed a total of 45 primer sets to amplify 99% of the coding region of the F8C gene and 41 of 50 splice junctions. After PCR amplification they used denaturing gradient gel electrophoresis (DGGE) to identify successfully the point mutations in 26 DNAs with different previously identified changes. Among 29 patients with unknown mutations, they identified the disease-producing change in 25 (86%). Two polymorphisms and 2 rare normal variants were also found. </p><p>Naylor et al. (1992) used an mRNA-based method to examine hemophilia A mutations and were able to explain the report of Higuchi et al. (1991) that mutations could not be identified in 14 of 30 severely affected patients, although mutations were found in all but 1 of 17 less severely affected patients. </p>

<p>Youssoufian et al. (1988) demonstrated the usefulness of DNA amplification followed by direct nucleotide sequencing in the search for mutations in X-linked disorders because of the unambiguous sequencing data obtained when the amplified DNA is from a male patient. In a 17-year-old Greek male with moderately severe hemophilia A (306700) (JH20), they detected a mutation by analysis of genomic DNA with TaqI; contrary to previous experience, the mutation was not a C-to-T or G-to-A transition. (The unifying mechanism of these mutations is thought to be methylation-induced C-to-T transitions at CpG dinucleotides involving either the coding or the complementary strand of DNA; see Bird (1980).) In this case the point mutation was in exon 7, where codon 291 for glutamate (GAA) was changed to one for glycine (GGA), leading to a change in amino acid 272 of the mature factor VIII protein. The mutation had arisen de novo in a germ cell of the patient's mother. The patient had 2% factor VIII activity, 3.5% factor VIII antigen, and moderate hemophilia A. </p>

The mutation affects the thrombin cleavage site. The same mutation was subsequently found in additional patients (JH38, JH39) by Arai et al. (1990). Aly et al. (1992) found that cysteamine, which is known to modify mutant proteins with an arg-to-cys substitution, enhances the procoagulant activity of the mutant factor VIII, which they referred to as factor VIII-East Hartford. Aly and Hoyer (1992) demonstrated that the East Hartford mutant protein had procoagulant activity when separated from von Willebrand factor; this was taken to indicate that the dissociation of factor VIII from VWF is an essential effect of factor VIII light chain cleavage at arginine-1689. </p>

Both patients had severe hemophilia A with less than 1% of normal factor VIII activity but with normal plasma level of factor VIII antigen. By denaturing gradient gel electrophoresis screening of PCR-amplified products of the factor VIII coding DNA sequence, followed by nucleotide sequencing of the abnormal PCR products, they identified in 1 patient a met1772-to-thr mutation that created a potential new N-glycosylation site at asparagine-1770 in the factor VIII light chain. In the second patient, an isoleucine-to-threonine substitution at position 566 created a potential new N-glycosylation site at asparagine-564 in the A2 domain of the factor VIII heavy chain. </p><p>Abnormal N-glycosylation, blocking factor VIII probe procoagulant activity, represented a previously unrecognized mechanism for the pathogenesis of severe hemophilia A.</p>

<p>Lakich et al. (1993) concluded that many mutations in the F8C gene result from recombination between homologous sequences within intron 22 of the F8C gene and those upstream of the gene. Such a recombination would lead to an inversion of all intervening DNA and a disruption of the gene. Among 23 patients with severe hemophilia A (306700), Naylor et al. (1993) found that approximately 40% were on the basis of this mutation involving intron 22. </p><p>It is hypothesized that the inversion mutations occur almost exclusively in germ cells during meiotic cell division by an intrachromosomal recombination between a 9.6-kb sequence within intron 22 and 1 of 2 almost identical copies located about 300 kb distal to the factor VIII gene at the telomeric end of the X chromosome. Most inversion mutations originate in male germ cells, where the lack of bivalent formation may facilitate flipping of the telomeric end of the single X chromosome. Oldenburg et al. (2000) reported the first instance of intron 22 inversion presenting as somatic mosaicism in a female, affecting only about 50% of lymphocyte and fibroblast cells of the proposita. Supposing a postzygotic de novo mutation as the usual cause of somatic mosaicism, the finding implies that the intron 22 inversion mutation is not restricted to meiotic cell divisions but can also occur during mitotic cell divisions, either in germ cell precursors or in somatic cells. </p><p>Lozier et al. (2002) found that the defect in the Chapel Hill hemophilia A dog colony started by Brinkhous and Graham (1950) replicates the F8 gene inversion commonly seen in humans with severe hemophilia A. </p>

<p>Bidichandani et al. (1994) studied 15 randomly selected hemophilia A (306700) patients, 9 of whom were severely affected. They reported a new mutation affecting the intron 6 splice donor site in the factor VIII gene of 2 patients, that corresponds to an exon skipping event involving exon 5 and 6. The mutation is an A-to-G substitution at position +3 in the splice donor site of intron 6 in both the patients. This exon skipping event left the translational frame intact, and the resultant in-frame deletion of 186-bp in the mature mRNA is predicted to cause a shortening of the mature factor VIII polypeptide by 62 amino acid residues. Direct sequencing showed that exon 5 is consistently skipped along with exon 6 in the mature factor VIII mRNA. Both patients have a disease of moderate severity and residual factor VIII activity 3% of the normal. Bidichandani et al. (1994) noted that a patient lacking exon 5 and 6 in the mature factor VIII mRNA due to gross DNA deletion has previously been reported to have severe hemophilia A. </p>

<p>Higuchi et al. (1991) and Diamond et al. (1992) identified this mutation in 2 patients with less than 1% factor VIII activity and severe-to-moderate hemophilia A (306700). The mutation was an AAT-to-AGT transition at codon 1922 in exon 18 of the F8 gene, resulting in an asn1922-to-ser (N1922S) substitution in the A3 domain of the protein. </p><p>Summers et al. (2011) noted that N1922 lies at the interface of 2 A3 subdomains in F8 and that the A3 and adjacent C1 domains form an extensive hydrophobic interface. By expression in baby hamster kidney cells, they found that F8 with the N1922S mutation (F8-N1922S) was weakly secreted compared with wildtype F8, although secreted F8-N1922S showed normal or near-normal activity. Wildtype F8 followed the classic secretory pathway; however, F8-N1922S was delayed in the endoplasmic reticulum (ER), prior to processing and packaging in the Golgi. Use of conformation-specific monoclonal antibodies revealed that the delay in the ER was due to a defect in folding of the A3 domain and the adjacent C1 domain. Summers et al. (2011) concluded that the N1922S substitution results in poor secretion of a functional protein. </p>

<p>Favier et al. (2000) described a 14-month-old girl with severe hemophilia A (306700). Both of her parents had normal values of factor VIII activity, and von Willebrand disease was excluded. Karyotype analysis demonstrated no obvious alteration, and no F8 gene inversions were found. Direct sequencing of the F8 gene exons revealed a frameshift-stop mutation (Q565delC/ter566) in the heterozygous state in the proposita only. F8 gene polymorphism analysis indicated that the mutation must have occurred de novo in the paternal germline. Furthermore, analysis of the pattern of X chromosome methylation at the human androgen receptor gene locus demonstrated a skewed inactivation of the derived maternal X chromosome from the lymphocytes of the proband's DNA. Thus, the severe hemophilia A in the proposita resulted from a de novo F8 gene mutation on the paternally derived X chromosome, associated with a nonrandom pattern of inactivation of the maternally derived X chromosome. </p>

<p>Sukarova et al. (2001) described a family with a severe form of hemophilia A (306700) in which they identified an Alu retrotransposition event in a coding exon, which represented the first report of an Alu insertion in the F8 gene. The propositus was an 18-year-old Bulgarian boy in whom the diagnosis of severe hemophilia had been made at the age of 1 year. His 12-year-old brother was also affected. There was no other family history of the disorder. The 341-bp element incorporated into the F8C gene interrupted the reading frame of the mature protein at met1224, resulting in a stop codon within the inserted sequence. Sequence analysis showed that the inserted fragment was a full Alu repeat belonging to the Yb8 subfamily of Alu repetitive sequences, according to the standardized nomenclature for Alu repeats (Batzer et al., 1996). The mutation site was flanked by a 5-bp (AAGAA) direct repeat which Sukarova et al. (2001) stated was the shortest direct repeat described at the integration points of Alu insertions. </p><p>Ganguly et al. (2003) reported a second instance: a 6-year-old male in whom an Alu element was inserted at position -19 of intron 18 of the F8C gene, causing skipping of exon 19 and hemophilia A. The insertion, which did not affect the natural splice donor site, was in the opposite orientation with respect to the direction of transcription of the F8 gene. The size of intron 18 was predicted to be increased by approximately 331 nucleotides because of the insertion. </p>

<p>In 2 unrelated probands with mild hemophilia A (HEMA; 306700), Jourdy et al. (2018) identified an intronic deletion (c.2113+461_2113+473del, NM_000132.3) in intron 13 of the F8 gene. Transcription analysis of patient cells showed an aberrant transcript resulting from this deletion; it caused the insertion of a 122-bp intronic fragment (c.2113_2114ins2113+477_2113+598) at the exon 13-14 junction. This out-of-frame insertion was predicted to result in a truncated protein (Gly705AspfsTer37). DNA sequencing analysis showed that the included pseudoexon corresponds to an antisense AluY element, and that the deletion removed a part of the poly(T)-tail from the right arm of AluY. The findings suggested aberrant exonization of the AluY element that likely resulted from decreased binding of the cryptic exon silencer HNRNPC (164020). Disruption of or siRNA-mediated knockdown of HNRNPC in HeLa cells reproduced the effect of the deletion. Screening of 992 unrelated French families with mild hemophilia A found a deletion in the poly(T)-tail of AluY in intron 13 in 6.1% of families, although these resulted from several different intronic deletions in this region, suggesting a recurring molecular mechanism. Haplotype analysis suggested a founder effect for c.2113+461_2113+473del. The patients also carried a normal F8 transcript in addition to the aberrant transcript, explaining the mild phenotype. </p>

(2021) identified a 23.4-kb tandem duplication in the F8 gene, including the promoter, exon 1, and part of intron 1. The mutation was hemizygous in affected males and heterozygous in affected females. The mutation was found by a combination of linkage analysis, MLPA analysis, whole-genome sequencing, and Sanger sequencing. The mutation segregated with disease in both families. The variant was not present in the 1000 Genomes Project database or in 103 control individuals. F8 mRNA was increased in patient lymphocytes. Increased transcriptional activity of fragments of the duplicated region was demonstrated via luciferase assay. The authors designated this mutation 'FVIII Padua.' </p>

To ensure long-term funding for the OMIM project, we have diversified
our revenue stream. We are determined to keep this website freely
accessible. Unfortunately, it is not free to produce. Expert curators
review the literature and organize it to facilitate your work. Over 90%
of the OMIM's operating expenses go to salary support for MD and PhD
science writers and biocurators. Please join your colleagues by making a
donation now and again in the future. Donations are an important
component of our efforts to ensure long-term funding to provide you the
information that you need at your fingertips.
