RCV000656826 | SCV000564849 | uncertain significance | not provided | 2018-01-19 | criteria provided, single submitter | clinical testing | This variant is denoted CDK4 c.364C>T at the cDNA level, p.Arg122Cys (R122C) at the protein level, and results in the change of an Arginine to a Cysteine (CGC>TGC). This variant has not, to our knowledge, been published in the literature as pathogenic or benign. CDK4 Arg122Cys was not observed at a significant allele frequency in large population cohorts (Lek 2016). CDK4 Arg122Cys is located in the protein kinase domain (UniProt). In-silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect. Based on currently available evidence, it is unclear whether CDK4 Arg122Cys is a pathogenic or benign variant. We consider it to be a variant of uncertain significance. |

RCV000815362 | SCV000955811 | uncertain significance | Familial melanoma | 2023-11-20 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 122 of the CDK4 protein (p.Arg122Cys). This variant is present in population databases (rs587778185, gnomAD 0.006%). 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: 133874). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The cysteine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect 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 | RCV001020800 | SCV001182327 | likely benign | Hereditary cancer-predisposing syndrome | 2024-12-06 | criteria provided, single submitter | clinical testing | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. |

RCV000663084 | SCV004020073 | uncertain significance | Melanoma, cutaneous malignant, susceptibility to, 3 | 2023-03-07 | criteria provided, single submitter | clinical testing | This variant is classified as a variant of uncertain significance as there is insufficient evidence to determine its impact on protein function and/or cancer risk. |
