Genes affected
TMEM266 (HGNC:26763): (transmembrane protein 266) Enables protein homodimerization activity. Predicted to be involved in transmembrane transport. Located in cytosol; dendrite; and plasma membrane. Is integral component of plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]
ETFA (HGNC:3481): (electron transfer flavoprotein subunit alpha) ETFA participates in catalyzing the initial step of the mitochondrial fatty acid beta-oxidation. It shuttles electrons between primary flavoprotein dehydrogenases and the membrane-bound electron transfer flavoprotein ubiquinone oxidoreductase. Defects in electron-transfer-flavoprotein have been implicated in type II glutaricaciduria in which multiple acyl-CoA dehydrogenase deficiencies result in large excretion of glutaric, lactic, ethylmalonic, butyric, isobutyric, 2-methyl-butyric, and isovaleric acids. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
