<p>Hydatidiform mole (HYDM; <a href="/entry/231090">231090</a>) is an abnormal gestation characterized by trophoblast hyperplasia and overgrowth of placental villi.

Expression of p57(KIP2) is restricted to the fetal adrenal cortex and presumably plays a role in controlling cell proliferation; its absence leads to adrenal cortex hyperplasia and cytomegaly. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=9144284" 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><p><a href="#14" class="mim-tip-reference" title="John, R.

Furthermore, fetuses and adult mice that inherited the deletion from their fathers were 20 to 25% smaller than their wildtype littermates. By contrast, maternal inheritance of this deletion had no effect on imprinted gene expression or growth. Thus, the unmethylated paternal KvDMR1 allele regulates imprinted expression by silencing genes on the paternal chromosome. These findings supported the hypothesis that loss of methylation in BWS patients activates the repressive function of KvDMR1 on the maternal chromosome, resulting in abnormal silencing of CDKN1C and the development of BWS. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=12410230" 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 variant was not present in the dbSNP (build 129) database. Inheritance of IMAGE syndrome was only through maternal transmission of the F276V mutation: sequencing in 24 family members confirmed that only individuals who inherited the 825T-G mutation on the maternal allele were affected, presumably due to epigenetic silencing of the mutated allele when it occurred on the paternal allele. Analysis of transfected HEK293 cells suggested disruption of PCNA binding. Overexpression of the F276V mutant in Drosophila resulted in moderate restriction of wing and eye growth, suggestive of a gain-of-function effect. <a href="https://pubmed.ncbi.nlm.nih.gov/?term=15769992+22634751" 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>
</h4>
</div>
<span class="mim-text-font">
<p>Hatada and Mukai (1995) showed that a mouse homolog of p57(KIP2) is genomically imprinted. The paternally inherited allele is transcriptionally repressed and methylated. The mouse gene maps to the distal region of chromosome 7, within a cluster of imprinted genes, including insulin-like growth factor-2 (IGF2; 147470) and H19 (103280). Matsuoka et al. (1996) demonstrated that the p57(KIP2) gene is imprinted in the human also. It is situated 500 kb centromeric to the IGF2 gene. The maternal allele is preferentially expressed; however, the imprint is not absolute, as the paternal allele is also expressed at low levels in most tissues and at levels comparable to the maternal allele in fetal brain and some embryonal tumors. It appears to lie in a domain containing other imprinted genes. Matsuoka et al. (1996) commented that establishment of an imprint may be coordinately regulated throughout the entire domain, as suggested by similar tissue-specific expression and imprinting patterns of IGF2, H19, and p57(KIP2) genes, while loss of imprinting (LOI) may not necessarily affect the entire region. </p><p>Du et al. (2003) confirmed the existence of insulators in the differentially methylated region (DMR) of the H19 gene and reported 2 insulators in the IGF2 gene. They also found 2 novel silencer sequences: 1 in KvDMR, a region that is thought to contain the promoter for the KCNQ1OT1 (604115) transcript, and the other in CDKN1C. The authors demonstrated binding of the zinc finger protein CTCF (604167) in vitro to all the insulator and silencer sequences detected. </p><p>Using primary human hematopoietic cells and microarray analysis, Scandura et al. (2004) identified p57(KIP2) as the only cyclin-dependent kinase inhibitor induced by TGF-beta (190180). Upregulation of p57 mRNA and protein occurred before TGF-beta-induced G1 cell cycle arrest, required transcription, and was mediated via a highly conserved region of the proximal p57 promoter. Upregulation of p57 was essential for TGF-beta-induced cell cycle arrest in these cells, since 2 different small interfering RNAs that prevented p57 upregulation blocked the cytostatic effects of TGF-beta on the hematopoietic cells. </p><p>In DNA from Beckwith-Wiedemann syndrome (BWS; 130650) patients with downregulated CDKN1C and normal methylation at KvDMR1, Diaz-Meyer et al. (2005) observed depletion of dimethylated H3-K4 (see 602810) and enrichment of dimethylated H3-K9 and HP1-gamma (604477) at the CDKN1C promoter, suggesting that in these cases gene silencing is associated with repressive chromatin changes. Diaz-Meyer et al. (2005) concluded that CDKN1C may be downregulated by multiple mechanisms including some that do not involve promoter methylation. </p><p>Using DNA microarrays to compare gene expression patterns in normal human placenta with those in other tissues, Sood et al. (2006) found that several genes involved in growth and tissue remodeling were expressed at relatively higher levels in the villus sections of placenta compared with other tissues. These included GPC3 (300037), CDKN1C, and IGF2. The GPC3 and CDKN1C genes are mutated in patients with Simpson-Golabi-Behmel syndrome (312870) and BWS, respectively, both fetal-placental overgrowth syndromes. In contrast, loss of IGF2 is associated with fetal growth restriction in mice. The relatively higher expression of genes that both promote and suppress growth suggested to Sood et al. (2006) tight and local regulation of the pathways that control placental development. </p><p>In mice, adult cardiomyocytes primarily express alpha-myosin heavy chain (alpha-MHC, also known as Myh6; 160710), whereas embryonic cardiomyocytes express beta-MHC (also known as Myh7; 160760). Cardiac stress triggers adult hearts to undergo hypertrophy and a shift from alpha-MHC to fetal beta-MHC expression. Hang et al. (2010) showed that BRG1 (603254), a chromatin-remodeling protein, has a critical role in regulating cardiac growth, differentiation, and gene expression. In embryos, Brg1 promotes myocyte proliferation by maintaining Bmp10 (608748) and suppressing p57(kip2) expression. It preserves fetal cardiac differentiation by interacting with histone deacetylases (HDACs; see 601241) and poly(ADP ribose) polymerase (PARP; 173870) to repress alpha-MHC and activate beta-MHC. In adults, Brg1 (also known as Smarca4) is turned off in cardiomyocytes. It is reactivated by cardiac stresses and forms a complex with its embryonic partners, HDAC and PARP, to induce a pathologic alpha-MHC-to-beta-MHC shift. Preventing Brg1 reexpression decreases hypertrophy and reverses this MHC switch. BRG1 is activated in certain patients with hypertrophic cardiomyopathy, its level correlating with disease severity and MHC changes. Hang et al. (2010) concluded that their studies showed that BRG1 maintains cardiomyocytes in an embryonic state, and demonstrated an epigenetic mechanism by which 3 classes of chromatin-modifying factors, BRG1, HDAC, and PARP, cooperate to control developmental and pathologic gene expression. </p>

<strong>Biochemical Features</strong>

<span class="mim-text-font">
<p>Hydatidiform mole (HYDM; 231090) is an abnormal gestation characterized by trophoblast hyperplasia and overgrowth of placental villi. The genetic basis in the vast majority of cases is an excess of paternal to maternal genomes, suggesting that global misexpression of imprinted genes is the common underlying molecular mechanism. Although most cases of complete HYDM are androgenetic in origin, a rare, frequently familial, biparental variant has been described. In a series of patients with biparental complete HYDM, Fisher et al. (2002) observed dramatic underexpression of CDKN1C identical to the pattern seen in complete HYDM of androgenetic origin. The series included 2 sisters, both of whom had biparental complete HYDM. Genotyping of this family identified a 15-cM region of homozygosity for 19q13.3-q13.4 similar to that found in 3 other families with recurrent biparental complete HYDM. Fisher et al. (2002) concluded that biparental complete HYDM, like complete HYDM of androgenetic origin, may result from abnormal expression of imprinted genes (such as CDKN1C), and that a locus on 19q13.3-q13.4 may regulate expression of imprinted genes on other chromosomes. </p>

<p><strong><em>Beckwith-Wiedemann Syndrome</em></strong></p><p>
Hatada et al. (1996) studied the p57(KIP2) gene in DNA samples from 9 unrelated Japanese patients with Beckwith-Wiedemann syndrome. They detected mutations in 2 BWS patients. In a 7-year-old boy with Beckwith Wiedemann syndrome (diagnosed on the basis of increased birth weight, omphalocele, macroglossia, intractable neonatal hypoglycemia, facial nevus flammeus, and earlobe grooves), PCR amplification and direct sequencing analysis led to identification of a heterozygous C-to-T transition at nucleotide 399, changing glutamine (CAG) to a termination codon (TAG) at position 47 (600856.0001). The mother was also heterozygous for the mutation but had inherited it from her father. She was phenotypically normal, since p57(KIP2) is expressed from the maternal allele (which was normal in her case). Hatada et al. (1996) also described a p57(KIP2) mutation in a 3-month-old girl with BWS. This patient was heterozygous for a T-to-AG change at nucleotide 1086 that modified the 9 amino acids downstream and resulted in a premature translation termination (600856.0002). In one other patient Hatada et al. (1996) demonstrated reduced expression of the p57(KIP2) gene in adrenal gland. Hatada et al. (1996) concluded that their studies provided evidence for a new mechanism for producing a phenotype with dominant transmission with little or no gene product: one allele with an inactive product is expressed and the other allele is repressed by genomic imprinting. Hatada et al. (1996) commented that other loci may possibly be involved in BWS since there are 3 other known balanced translocations leading to BWS which map several megabases from the p57(KIP2) region. </p><p>By complete sequencing of the coding exons and intron/exon junctions of the CDKN1C gene, O'Keefe et al. (1997) found a maternally transmitted coding mutation in the CDK-inhibitor domain of the KIP2 gene in 1 of 5 cases of BWS. The mutation was an in-frame 3-amino acid deletion that significantly reduced but did not fully abrogate growth-suppressive activity in transfection assay. In contrast, no somatic coding mutations from KIP2 were found in a set of 12 primary Wilms tumors enriched for cases that expressed KIP2 mRNA, including cases with and without 11p15.5 loss of heterozygosity. Lee et al. (1997) analyzed the entire coding sequence and intron/exon boundaries of p57(KIP2) in 40 unrelated BWS patients. Only 2 (5%) showed mutations, both involving frameshifts in the second exon. In 1 case, the mutation was transmitted to the proband's mother, who was also affected, from the maternal grandfather, suggesting that this gene is not imprinted, at least in some affected tissues, at a critical stage of development and that haploinsufficiency due to mutation of either parental allele may cause at least some features of BWS. The low frequency of p57(KIP2) mutations, as well as the discovery of disruption of the LQT1 gene (see 607542) in patients with chromosomal rearrangements, suggests that BWS can involve disruption of multiple independent genes on 11p15.5 </p><p>Hatada et al. (1997) screened for mutations in the p57(KIP2) gene in 15 additional BWS patients and found 2 with mutations in this gene (e.g., 600856.0003). The rate of mutations was thus 4 in 24 cases, or 17%. </p><p>Lam et al. (1999) sequenced the CDKN1C gene in 70 patients with BWS. Fifty-four were sporadic with no evidence of uniparental disomy and 16 were familial from 7 kindreds. Novel germline CDKN1C mutations were identified in 5 probands, 3 of 7 familial cases and 2 of 54 sporadic cases. There was no association between germline CDKN1C mutations and IGF2 or H19 abnormalities. There was a significantly higher frequency of exomphalos in the CDKN1C mutation cases as compared to cases with other types of molecular pathology. There was no association between germline CDKN1C mutations and risk of embryonal tumors. No CDKN1C mutations were identified in 6 non-BWS patients with overgrowth and Wilms tumor. </p><p>Algar et al. (1999) reported 2 patients with mosaic paternal isodisomy of the 11p15 region. These patients had reduced levels of CDKN1C expression in the liver and kidney, respectively. Some expression from the paternally derived CDKN1C allele was evident, consistent with incomplete paternal imprinting. One patient showed maternal allele silencing, in addition to allele imbalance. Algar et al. (1999) concluded that CDKN1C expression is reduced in patients with BWS with allele imbalance, and suggested that CDKN1C haploinsufficiency contributes to the BWS phenotype in patients with mosaic paternal isodisomy of chromosome 11. </p><p>Algar et al. (2000) examined 32 patients with BWS for mutations affecting the CDKN1C gene, including 7 cases of familial BWS. No mutations were detected in the coding region of the gene in any case; however, in 2 patients, 2 G-A base substitutions at adjacent positions in the 5-prime untranslated region were detected. These substitutions were also found in normal controls. In 3 of 18 cases studied by semiquantitative RT-PCR, CDKN1C expression was significantly reduced in the peripheral blood compared with controls. These and other results suggested that biallelic CDKN1C expression does not significantly perturb the overall levels of CDKN1C expression in somatic tissue. The results also confirmed other studies showing that the mechanisms associated with regulating CDKN1C expression and imprinting are separate from those regulating IGF2 imprinting. </p><p>Romanelli et al. (2010) identified 7 novel mutations in the CDKN1C gene in 8 of 50 patients with BWS who did not have epigenetic alterations at chromosome 11q15. Six patients inherited the mutation from apparently asymptomatic mothers, 1 was de novo, and 1 could not be determined. Three of the mutations involved nucleotide 845 (see, e.g., 600856.0004 and 600856.0005), suggesting a possible mutation hotspot. In additional to classic features of the disorder, 2 patients had polydactyly, 2 had an extra nipple, and 3 had cleft palate. No mutations were found in 22 patients with isolated hemihypertrophy, omphalocele, or macroglossia. </p><p><strong><em>IMAGE Syndrome</em></strong></p><p>
In affected members of a 5-generation Argentinian family with intrauterine growth restriction, metaphyseal dysplasia, adrenal hypoplasia congenita, and genital anomalies (IMAGE syndrome; 614732) and 4 additional unrelated patients, Arboleda et al. (2012) identified heterozygous mutations in the CDKN1C gene (600856.0007-600856.0011). All 5 IMAGE-associated mutations are clustered in a highly conserved region of CDKN1C, near the PCNA (176740)-binding domain, and result in loss of PCNA binding. Targeted expression of IMAGE-associated CDKN1C mutations in Drosophila caused restricted eye and wing growth, suggesting a gain-of-function mechanism. Familial analysis showed an imprinted mode of inheritance in the Argentinian family, in which only maternal transmission of the mutation resulted in IMAGE syndrome. </p><p><strong><em>Association with Cancer</em></strong></p><p>
Tokino et al. (1996) examined the CDKN1C gene for genetic alterations in a large number of tumors. Although no somatic mutation was detected, they found several normal variations in this gene, including 4 types of 12-bp in-frame deletions in the proline/alanine repeating domain. </p>

<p>Zhang et al. (1997) produced targeted disruption of the p57(KIP2) gene in mice and demonstrated that they have altered cell proliferation and differentiation, leading to abdominal muscle defects; cleft palate; endochondral bone ossification defects with incomplete differentiation of hypertrophic chondrocytes; renal medullary dysplasia; adrenal cortical hyperplasia and cytomegaly; and lens cell hyperproliferation and apoptosis. Since many of these phenotypes are observed in patients with BWS, Zhang et al. (1997) suggested that the observations support a loss of p57(KIP2) expression as having a role in that disorder. Zhang et al. (1997) noted that type X collagen (120110) is expressed in hypertrophic chondrocytes and has been implicated in proper bone development. In mutant mice, expression of type X collagen was significantly reduced in the mutant hypertrophic zone. Thus, the investigators concluded that p57(KIP2) is required for expression of collagen X, and perhaps other genes that facilitate the ossification of chondrocytes. Expression of p57(KIP2) is restricted to the fetal adrenal cortex and presumably plays a role in controlling cell proliferation; its absence leads to adrenal cortex hyperplasia and cytomegaly. </p><p>John et al. (2001) used transgenic mice harboring modified BAC inserts to show that enhancers for expression (within skeletal muscle and cartilage) of the mouse p57Kip2 (Cdkn1c) gene were located at least 25 kb downstream. There was no evidence for allele-specific expression of Cdkn1c from BAC transgenes that spanned 315 kb around the locus. The authors suggested that a key imprinting element for Cdkn1c, as for IGF2, may lie at a distance, and hypothesized that Beckwith-Wiedemann syndrome in humans may result from disruption of appropriate expression of CDKN1C through mutations that occur at a substantial distance from the gene. </p><p>One-third of individuals with Beckwith-Wiedemann syndrome lose maternal-specific methylation at KvDMR1, a putative imprinting control region within intron 10 of the KCNQ1 gene (607542), and it has been proposed that this epimutation results in aberrant imprinting and, consequently, BWS. Fitzpatrick et al. (2002) showed that paternal inheritance of this mutation in mice results in the derepression in cis of 6 genes, including Cdkn1c. Furthermore, fetuses and adult mice that inherited the deletion from their fathers were 20 to 25% smaller than their wildtype littermates. By contrast, maternal inheritance of this deletion had no effect on imprinted gene expression or growth. Thus, the unmethylated paternal KvDMR1 allele regulates imprinted expression by silencing genes on the paternal chromosome. These findings supported the hypothesis that loss of methylation in BWS patients activates the repressive function of KvDMR1 on the maternal chromosome, resulting in abnormal silencing of CDKN1C and the development of BWS. </p>

<p>Hatada et al. (1996) identified a heterozygous glu47-to-ter mutation in a 7-year-old boy with BWS (130650) caused by a C-to-T transition at nucleotide 399. They noted that this mutation would lead to a severely truncated polypeptide of 46 residues with disruption of the Cdk inhibitory domain and loss of the QT domain and the proline/alanine repeats. This mutation disrupts a PstI restriction site; digestion of the PCR-amplified DNA with PstI led to the identification of a novel 219-bp fragment in the patient in addition to 3 other fragments which were also detected in normal individuals. The parents, grandparents, and sister of the patient were healthy. PCR-amplified DNA from the parents was examined, and the mother was found to have the same 219-bp fragment that was present in the mutant allele of the patient. The father of the patient had only the normal allele. Hatada et al. (1996) reported that the mother inherited the abnormal allele from her father. She was phenotypically normal, since p57(KIP2) is expressed from the maternal allele. </p><p>By functional analysis of the glu47-to-ter mutation in the patient reported by Hatada et al. (1996), Bhuiyan et al. (1999) found that the mutation, which occurs in the Cdk inhibitory domain, renders the protein inactive with consequent complete loss of its role as a cell cycle inhibitor and of its nuclear localization. </p>

The variant was not present in the dbSNP (build 129) database. Inheritance of IMAGE syndrome was only through maternal transmission of the F276V mutation: sequencing in 24 family members confirmed that only individuals who inherited the 825T-G mutation on the maternal allele were affected, presumably due to epigenetic silencing of the mutated allele when it occurred on the paternal allele. Analysis of transfected HEK293 cells suggested disruption of PCNA binding.

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.
