Hereditary diffuse gastric adenocarcinoma Uncertain:1
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. 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: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with CDH1-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces cysteine with tyrosine at codon 163 of the CDH1 protein (p.Cys163Tyr). The cysteine residue is moderately conserved and there is a large physicochemical difference between cysteine and tyrosine. -
Hereditary cancer-predisposing syndrome Uncertain:1
The p.C163Y variant (also known as c.488G>A), located in coding exon 4 of the CDH1 gene, results from a G to A substitution at nucleotide position 488. The cysteine at codon 163 is replaced by tyrosine, an amino acid with highly dissimilar properties. This amino acid position is not well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this alteration remains unclear. -
