Color Diagnostics, LLC DBA Color Health RCV001183955 SCV001349813 uncertain significance Hereditary cancer-predisposing syndrome 2019-10-22 criteria provided, single submitter clinical testing This missense variant replaces arginine with glutamine at codon 80 of the CDKN2A protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). Splice site prediction tools suggest that this variant may not impact RNA splicing. To our knowledge, functional studies have not been performed for this variant. This variant has not been reported in individuals affected with hereditary cancer in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.
Labcorp Genetics (formerly Invitae), Labcorp RCV001495364 SCV001700046 uncertain significance Familial melanoma 2022-02-27 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 80 of the CDKN2A (p16INK4a) protein (p.Arg80Gln). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with CDKN2A (p16INK4a)-related conditions. ClinVar contains an entry for this variant (Variation ID: 376385). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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 RCV001183955 SCV002732548 uncertain significance Hereditary cancer-predisposing syndrome 2023-05-10 criteria provided, single submitter clinical testing The p.R80Q variant (also known as c.239G>A), located in coding exon 2 of the CDKN2A gene, results from a G to A substitution at nucleotide position 239. The arginine at codon 80 is replaced by glutamine, an amino acid with highly similar 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.
