RCV001332338 | SCV002253163 | uncertain significance | Mitochondrial DNA depletion syndrome, encephalomyopathic form with methylmalonic aciduria | 2022-08-15 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 424 of the SUCLA2 protein (p.Gly424Arg). This variant is present in population databases (rs144441199, gnomAD 0.05%). 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: 1030716). 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: "Benign"; Align-GVGD: "Class C0"). 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. |
Ambry Genetics | RCV004035736 | SCV004959941 | uncertain significance | Inborn genetic diseases | 2023-10-14 | criteria provided, single submitter | clinical testing | The c.1270G>A (p.G424R) alteration is located in exon 10 (coding exon 10) of the SUCLA2 gene. This alteration results from a G to A substitution at nucleotide position 1270, causing the glycine (G) at amino acid position 424 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
