Invitae | RCV000692990 | SCV000820843 | uncertain significance | Mitochondrial complex V (ATP synthase) deficiency nuclear type 2 | 2022-04-20 | criteria provided, single submitter | clinical testing | This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 147 of the TMEM70 protein (p.Ile147Thr). This variant is present in population databases (rs201306262, gnomAD 0.05%). This missense change has been observed in individual(s) with long QT syndrome (LQTS) and hypertrophic cardiomyopathy (HCM) (PMID: 25825456). ClinVar contains an entry for this variant (Variation ID: 571761). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C25". The threonine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. |
