Description

This variant has not been reported in the literature in individuals affected with DES-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces glycine with aspartic acid at codon 437 of the DES protein (p.Gly437Asp). The glycine residue is moderately conserved and there is a moderate physicochemical difference between glycine and aspartic acid. ClinVar contains an entry for this variant (Variation ID: 239074). 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: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0").
