Genes affected
SUCLG1 (HGNC:11449): (succinate-CoA ligase GDP/ADP-forming subunit alpha) This gene encodes the alpha subunit of the heterodimeric enzyme succinate coenzyme A ligase. This enzyme is targeted to the mitochondria and catalyzes the conversion of succinyl CoA and ADP or GDP to succinate and ATP or GTP. Mutations in this gene are the cause of the metabolic disorder fatal infantile lactic acidosis and mitochondrial DNA depletion. [provided by RefSeq, Feb 2010]

Uncertain significance, criteria provided, single submitterclinical testingGeneDxDec 18, 2012p.Leu318Phe (CTT>TTT): c.952 C>T in exon 8 of the SUCLG1 gene (NM_003849.3) A variant of unknown significance has been identified in the SUCLG1 gene. The L318F missense substitution has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The amino acid change is conservative in that both Leucine and Phenylalanine are uncharged, non-polar amino acids. This change occurs at a position in the SUCLG1 protein that is conserved in mammals. In-silico analysis models predict that L318F is damaging to the SUCLG1 protein. Therefore, based on the currently available information, it is unclear whether L318F is a disease-causing mutation or a rare benign variant. The variant is found in MITONUC-MITOP panel(s). -
