Labcorp Genetics (formerly Invitae), Labcorp RCV002672222 SCV002991910 uncertain significance Mitochondrial hypertrophic cardiomyopathy with lactic acidosis due to MTO1 deficiency 2022-08-05 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 68 of the MTO1 protein (p.Arg68Cys). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MTO1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly 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.
