Ambry Genetics RCV000131408 SCV000186384 uncertain significance Hereditary cancer-predisposing syndrome 2024-04-13 criteria provided, single submitter clinical testing The p.Y797C variant (also known as c.2390A>G), located in coding exon 15 of the CDH1 gene, results from an A to G substitution at nucleotide position 2390. The tyrosine at codon 797 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.

Therefore, it has been classified as a Variant of Uncertain Significance. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 142338). This variant has not been reported in the literature in individuals affected with CDH1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 797 of the CDH1 protein (p.Tyr797Cys).
