Labcorp Genetics (formerly Invitae), Labcorp RCV001864920 SCV002126823 uncertain significance Hereditary diffuse gastric adenocarcinoma 2021-06-11 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. This sequence change replaces alanine with arginine at codon 617 of the CDH1 protein (p.Ala617Arg). The alanine residue is weakly conserved and there is a moderate physicochemical difference between alanine and arginine. The frequency data for this variant in the population databases is not available, as this variant may be reported as separate entries in the ExAC database. This variant has not been reported in the literature in individuals with CDH1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available"). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies.
