Genes affected
CDKN1C (HGNC:1786): (cyclin dependent kinase inhibitor 1C) This gene is imprinted, with preferential expression of the maternal allele. The encoded protein is a tight-binding, strong inhibitor of several G1 cyclin/Cdk complexes and a negative regulator of cell proliferation. Mutations in this gene are implicated in sporadic cancers and Beckwith-Wiedemann syndorome, suggesting that this gene is a tumor suppressor candidate. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Oct 2010]

Submissions by phenotype

Beckwith-Wiedemann syndrome Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingInvitaeJan 21, 2024This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 117 of the CDKN1C protein (p.Pro117Ser). This variant is present in population databases (rs570636789, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with CDKN1C-related conditions. ClinVar contains an entry for this variant (Variation ID: 453994). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt CDKN1C protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
