Labcorp Genetics (formerly Invitae), Labcorp RCV001233975 SCV001406597 uncertain significance Combined oxidative phosphorylation defect type 27 2022-04-07 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 are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This sequence change replaces serine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 221 of the CARS2 protein (p.Ser221Cys). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with CARS2-related conditions. ClinVar contains an entry for this variant (Variation ID: 960449).
