Description

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 74 of the MRPS16 protein (p.Arg74Cys). 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 output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C55". The cysteine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with MRPS16-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.004%).
