| Invitae | RCV000533639 | SCV000637367 | uncertain significance | Familial melanoma | 2022-07-19 | criteria provided, single submitter | clinical testing | 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. 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 CDK4 protein function. ClinVar contains an entry for this variant (Variation ID: 463463). This variant has not been reported in the literature in individuals affected with CDK4-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 7 of the CDK4 protein (p.Glu7Lys). |

| Ambry Genetics | RCV002420412 | SCV002724191 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-10-19 | criteria provided, single submitter | clinical testing | The p.E7K variant (also known as c.19G>A), located in coding exon 1 of the CDK4 gene, results from a G to A substitution at nucleotide position 19. The glutamic acid at codon 7 is replaced by lysine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
