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 do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C15"). This variant has not been reported in the literature in individuals with CASR-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces asparagine with aspartic acid at codon 155 of the CASR protein (p.Asn155Asp). The asparagine residue is highly conserved and there is a small physicochemical difference between asparagine and aspartic acid. |
