RCV002042868 | SCV002291929 | uncertain significance | Familial melanoma | 2021-01-10 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals with CDK4-related conditions. This variant, c.135_143dup, results in the insertion of 3 amino acid(s) to the CDK4 protein (p.Gly46_Gly48dup), but otherwise preserves the integrity of the reading frame. This variant is not present in population databases (ExAC no frequency). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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 | RCV003170533 | SCV003870470 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-11-18 | criteria provided, single submitter | clinical testing | The c.135_143dupTGGAGGAGG variant (also known as p.G46_G48dup), located in coding exon 1 of the CDK4 gene, results from an in-frame duplication of TGGAGGAGG at nucleotide positions 135 to 143. This results in the duplication of 3 extra residues (GGG) between codons 46 and 48. This amino acid region is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive (Choi Y et al. PLoS ONE. 2012; 7(10):e46688). Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
