Description

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 524 of the CDH1 protein (p.Arg524Gln). This variant is present in population databases (rs761180883, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with CDH1-related conditions. ClinVar contains an entry for this variant (Variation ID: 230993). 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 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.
