Invitae RCV000557741 SCV000650876 uncertain significance Mitochondrial complex V (ATP synthase) deficiency nuclear type 2 2019-07-04 criteria provided, single submitter clinical testing In summary, this variant has uncertain impact on TMEM70 function. The available evidence is currently insufficient to determine its role 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 do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with a TMEM70-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces valine with isoleucine at codon 167 of the TMEM70 protein (p.Val167Ile). The valine residue is highly conserved and there is a small physicochemical difference between valine and isoleucine.
