Genes affected

SUCLG2 (HGNC:11450): (succinate-CoA ligase GDP-forming subunit beta) This gene encodes a GTP-specific beta subunit of succinyl-CoA synthetase. Succinyl-CoA synthetase catalyzes the reversible reaction involving the formation of succinyl-CoA and succinate. Alternate splicing results in multiple transcript variants. Pseudogenes of this gene are found on chromosomes 5 and 12. [provided by RefSeq, Apr 2010]

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 392 of the SUCLG2 protein (p.Arg392Gln). This variant is present in population databases (rs180701292, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with SUCLG2-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. 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. -
