The disease is pyruvate dehydrogenase E3-binding protein deficiency (MONDO_0009503). Also known as: 2-oxoglutarate complex deficiency, Glycine cleavage system L protein deficiency, branched chain alpha-ketoacid dehydrogenase complex deficiency, diaphorase deficiency, dihydrolipoyl dehydrogenase deficiency, lacticacidemia due to PDX1 deficiency, lipoamide dehydrogenase deficiency, pyruvate dehydrogenase complex component E3 deficiency.
