Labcorp Genetics (formerly Invitae), Labcorp RCV002575762 SCV002938480 uncertain significance Mitochondrial complex V (ATP synthase) deficiency nuclear type 2 2022-02-23 criteria provided, single submitter clinical testing 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 output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with TMEM70-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 140 of the TMEM70 protein (p.Ile140Val).
