Description

Has not been previously published as pathogenic or benign to our knowledge; Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect

Description

This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 198 of the NDUFS8 protein (p.Glu198Lys). 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 1305656). This variant has not been reported in the literature in individuals affected with NDUFS8-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.003%).
