Submissions by phenotype
not provided Uncertain:2
Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
The CDK4 c.800C>T (p.Ser267Leu) variant has been reported in the published literature in a female with breast cancer (PMID: 25186627 (2015)) and a female with ovarian cancer who also had other variants of uncertain significance in cancer predisposition genes (PMID: 38509102 (2024)). The frequency of this variant in the general population, 0.0000066 (1/152168 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is benign. Based on the available information, we are unable to determine the clinical significance of this variant. -
Hereditary cancer-predisposing syndrome Uncertain:1
The p.S267L variant (also known as c.800C>T), located in coding exon 6 of the CDK4 gene, results from a C to T substitution at nucleotide position 800. The serine at codon 267 is replaced by leucine, an amino acid with dissimilar properties. This amino acid position is not well conserved in available vertebrate species. 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. -
Familial melanoma Uncertain:1
This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 267 of the CDK4 protein (p.Ser267Leu). 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: 439048). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt CDK4 protein function with a negative predictive value of 95%. 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. -
