Labcorp Genetics (formerly Invitae), Labcorp RCV001301242 SCV001490406 uncertain significance Mitochondrial DNA depletion syndrome, encephalomyopathic form with methylmalonic aciduria 2022-02-05 criteria provided, single submitter clinical testing This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 203 of the SUCLA2 protein (p.Ile203Val). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SUCLA2-related conditions. ClinVar contains an entry for this variant (Variation ID: 1004526). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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.
