Description

Published functional studies suggest a damaging effect (protein instability and altered localization) (PMID: 20593814, 19409522); 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; This variant is associated with the following publications: (PMID: 25269795, 26018198, 33144682, 19409522, 26944241, 34758253, 20593814, 28155230)

Description

For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects GFER function (PMID: 19409522, 25269795). 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: 8691). This missense change has been observed in individuals with mitochondrial myopathy (PMID: 19409522, 26018198, 26944241). It has also been observed to segregate with disease in related individuals. This variant is present in population databases (rs121908192, gnomAD 0.01%). This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 194 of the GFER protein (p.Arg194His).
