Description

This sequence change replaces serine, which is neutral and polar, with glycine, which is neutral and non-polar, at codon 370 of the COQ8A protein (p.Ser370Gly). This variant is present in population databases (rs180784380, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with COQ8A-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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.

Description

Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
