Description

This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 364 of the COQ8A protein (p.Val364Met). This variant is present in population databases (rs371269974, gnomAD 0.007%). This variant has not been reported in the literature in individuals affected with COQ8A-related conditions. ClinVar contains an entry for this variant (Variation ID: 1355418). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt COQ8A protein function. 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
