Invitae RCV001213880 SCV001385532 uncertain significance Familial melanoma 2023-10-23 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 195 of the CDK4 protein (p.Val195Met). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with CDK4-related conditions. ClinVar contains an entry for this variant (Variation ID: 943646). 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 expected to disrupt CDK4 protein function. 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.
Ambry Genetics RCV002356914 SCV002650849 uncertain significance Hereditary cancer-predisposing syndrome 2022-08-30 criteria provided, single submitter clinical testing The p.V195M variant (also known as c.583G>A), located in coding exon 4 of the CDK4 gene, results from a G to A substitution at nucleotide position 583. The valine at codon 195 is replaced by methionine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
