The nonsense mutation was predicted to produce a truncated protein missing 20 C-terminal amino acids based on homology to other homeodomains whose 3-dimensional structures had been determined. This portion of the normal homeodomain folds into the last of the 3 alpha-helices. This helix is critical for DNA binding. The authors noted that the tryptophan that was mutated in this family is the only amino acid which is invariant in all known homeodomain proteins. <a href="https://pubmed.ncbi.nlm.nih.gov/?term=5450271+9020844" 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>

<strong>Gene Function</strong>

<span class="mim-text-font">
<p>Rinn et al. (2008) stated that fibroblasts obtained from anatomically distinct sites of human skin express genes in a site-specific manner. By microarray analysis of cultured fibroblasts derived from foot or thigh, followed by comparing gene expression profiles of primary fibroblasts from 43 anatomic sites, Rinn et al. (2008) found that HOXA13 expression was associated with distal sites and was required for activation of distal-specific gene expression, including expression of WNT5A (164975). Depletion of HOXA13 in human plantar fibroblasts reduced expression of distal-specific keratin-9 (KRT9; 607606), and KRT9 expression was rescued by addition of recombinant purified WNT5A. In situ hybridization showed that Hoxa13 and Wnt5a were spatially and temporally coexpressed in distal limb bud during mouse development. Rinn et al. (2008) concluded that HOXA13 control of WNT5A expression in distal fibroblasts can regulate site-specific epidermal differentiation. </p><p>Sheth et al. (2012) used mouse genetics to analyze how digit patterning (an iterative digit/nondigit pattern) is generated and showed that the progressive reduction in Hoxa13 and Hoxd11 (142986)-Hoxd13 (142989) genes (hereafter referred to as distal Hox genes) from the Gli3 (165240)-null background results in progressively more severe polydactyly, displaying thinner and densely packed digits. Combined with computer modeling, their results argued for a Turing-type mechanism underlying digit patterning, in which the dose of distal Hox genes modulates the digit period or wavelength. The phenotypic similarity of fish-fin endoskeleton patterns suggested that the pentadactyl state has been achieved through modification of an ancestral Turing-type mechanism. </p><p>Kherdjemil et al. (2016) showed that the mutually exclusive expression of the mouse genes Hoxa11 (142958) and Hoxa13, which had been proposed to be involved in the origin of the tetrapod limb, is required for the pentadactyl state. Kherdjemil et al. (2016) further demonstrated that the exclusion of Hoxa11 from the Hoxa13 domain relies on an enhancer that drives antisense transcription at the Hoxa11 locus after activation by Hoxa13 and Hoxd13. Finally, the authors showed that the enhancer that drives antisense transcription of the mouse Hoxa11 gene is absent in zebrafish, which, together with the largely overlapping expression of hoxa11 and hoxa13 genes reported in fish, suggested that this enhancer emerged in the course of the fin-to-limb transition. On the basis of the polydactyly that was observed after expression of Hoxa11 in distal limbs, Kherdjemil et al. (2016) proposed that the evolution of Hoxa11 regulation contributed to the transition from polydactyl limbs in stem-group tetrapods to pentadactyl limbs in extant tetrapods. </p>

<p>Mortlock (1996) found a mutation in the HOXA13 gene resulting in hand-foot-uterus (HFU) syndrome, also known as hand-foot-genital (HFG) syndrome (140000). Their observations were made in the family reported by Stern et al. (1970). This was the second mutation discovered in a HOX gene as the cause of a malformation; the first to be discovered was the mutation in HOXD13 (142989) as the cause of synpolydactyly (186000). </p><p>Mortlock and Innis (1997) found that affected members of an HFG syndrome family reported by Stern et al. (1970) had a mutation in the HOXA13 gene that converted a highly conserved tryptophan residue in the homeodomain to a stop codon with resulting truncation of 20 amino acids from the protein (142959.0001). It was thought that the mutation probably eliminated or greatly reduced the ability of the protein to bind to DNA. </p><p>Goodman et al. (2000) examined the HOXA13 gene in 2 new and 4 previously reported families with features of HFG syndrome. In 3 families, nonsense mutations truncating the encoded protein N-terminal to or within the homeodomain produced typical limb and genitourinary abnormalities; in the fourth family, an expansion of an N-terminal polyalanine tract produced a similar phenotype; in the fifth family, a missense mutation, which altered an invariant domain, produced an exceptionally severe limb phenotype; and in the sixth family, in which limb abnormalities were atypical, no HOXA13 mutation was detected. </p><p>The polyalanine expansion reported by Goodman et al. (2000) occurred in exon 1 following nucleotide 388 and resulting in the in-frame insertion of 24-bp and an additional 8 alanine residues (142959.0003). Utsch et al. (2002) reported a similar in-frame expansion of 6 alanines also in exon 1, following nucleotide 376, of the HOXA13 gene (142959.0006). They pointed out that expansion by 7 up to 14 alanine residues occurs in the HOXD13 gene, resulting in synpolydactyly. </p><p>Guttmacher syndrome (176305) has a number of features in common with hand-foot-genital syndrome, including hypoplastic thumbs and halluces, fifth-finger clinobrachydactyly, and hypospadias. However, 2 of its features, postaxial polydactyly of the hands and short or uniphalangeal second toes with absent nails, had never been observed in patients with hand-foot-genital syndrome. Because of the similarities, Innis et al. (2002) reinvestigated the family originally described by Guttmacher (1993). They found that affected individuals were heterozygous for a novel missense mutation in the HOXA13 homeobox (Q50L; 142959.0005), which arose on an allele already carrying a novel 2-bp deletion (involving GC at positions -78 and -79) in the gene's highly conserved promoter region. This promoter deletion produces no detectable abnormalities on its own, but may have contributed to the phenotype in the affected individuals. The missense mutation, which altered a key residue in the recognition helix of the homeodomain, is likely to perturb HOXA13's DNA-binding properties, resulting in both a loss and a specific gain of function. </p>

<p>Mortlock et al. (1996) found a 50-bp deletion in the first exon of the Hoxa13 gene in mice with the semidominant mutation 'Hypodactyly' (Hd). The mutation was known to map to a genetic interval overlapping the Hoxa cluster on mouse chromosome 6. They stated that the deletion probably arose from unequal recombination between triplet repeats. </p><p>Innis et al. (2004) performed homologous recombination in murine embryonic stem cells to expand the size of the third largest polyalanine tract by 10 residues. Mutant mice were indistinguishable from Hoxa13-null mice. Mutant limb buds had normal steady-state Hoxa13 RNA expression, normal mRNA splicing, and reduced levels of steady-state protein. In vitro translation efficiency of the mutant protein was normal. Innis et al. (2004) concluded that loss of function was secondary to reduced levels of the expanded protein in vivo, likely due to degradation. </p><p>Late limb buds of all tetrapods contain 3 proximodistal segments, each expressing specific homeobox genes. The stylopod (upper limb) expresses Meis1/2 (see 601739), the zeugopod (lower limb) expresses Hoxa11 (142958), and the autopod (hand/foot) Hoxa13, although none of these markers is sufficient to specify limb-segment identity (summary by Rosello-Diez et al., 2011). Cooper et al. (2011) showed that Wnt3a (606359), Fgf8 (600483), and retinoic acid act together to maintain markers of early limb mesenchyme in culture. Rosello-Diez et al. (2011) showed that the first limb bud proximodistal regionalization results from the balance between proximal and distal signals. The results of both groups suggested that retinoic acid is the trunk proximalizing signal and that the trigger for initiating the process of specification of the zeugopod and autopod is the cessation (due to displacement) of retinoic acid exposure, and argued against a mechanism linking proximodistal specification to a cell cycle-based internal clock. </p><p>Roux et al. (2019) found that mice with conditional knockout of Hoxa13 displayed megaureter phenotype due to abnormal ureter insertion caused by defective common nephric duct elimination. The severity of the hydroureter phenotype was likely associated with delayed ureter maturation in Hoxa13 mutant mice. In addition, Hoxa13 mutant mice displayed defective Mullerian duct fusion similar to that found in female patients with HFG syndrome. In situ hybridization analysis revealed that Hoxa13 acted upstream of Ret (164761) and Gata3 (131320) and impacted Ret expression through Gata3. Furthermore, Gata3 played a mediator role on Hoxa13 function in the urogenital sinus. </p>

<p>Mortlock and Innis (1997) found that patients with the hand-foot-genital syndrome (HFG; 140000) in the family reported by Stern et al. (1970) had an A-to-G transition in a highly conserved tryptophan codon in the HOXA13 homeodomain, which, in addition to causing a trp369-to-ter substitution (TGG to TGA), also destroyed a NlaIV restriction site. The nonsense mutation was predicted to produce a truncated protein missing 20 C-terminal amino acids based on homology to other homeodomains whose 3-dimensional structures had been determined. This portion of the normal homeodomain folds into the last of the 3 alpha-helices. This helix is critical for DNA binding. The authors noted that the tryptophan that was mutated in this family is the only amino acid which is invariant in all known homeodomain proteins. </p>

<p>Goodman et al. (2000) identified a nonsense truncating mutation in a male patient who had hand and foot abnormalities typical of hand-foot-genital syndrome (HFG; 140000), as well as a short penis tethered inferiorly to the scrotal sac. The predicted truncated protein in this individual lacked the entire homeodomain of the HOXA13 protein. The proband was heterozygous for an A-to-C substitution in exon 1 at base 407 (number of bases starting at the first residue of the initiated codon). The mutation converted a serine residue to a stop codon and was predicted to result in a truncated protein containing only the first 135 amino acids of the wildtype protein. </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.
