Neonatal encephalomyopathy-cardiomyopathy-respiratory distress syndrome Uncertain:1
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: "Probably Damaging"; Align-GVGD: "Class C0"). 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. This variant has not been reported in the literature in individuals with COQ4-related disease. This variant is present in population databases (rs765791496, ExAC 0.002%). This sequence change replaces glutamine with histidine at codon 48 of the COQ4 protein (p.Gln48His). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and histidine. -
