Summaries for Hypervalinemia and Hyperleucine-Isoleucinemia

OMIM : 56 Hypervalinemia and hyperleucine-isoleucinemia (HVLI) is a branched-chain amino acid metabolic disorder characterized by highly elevated plasma valine and leucine concentrations. The patient presented in adulthood with headache and mild memory impairment, and had abnormal symmetric white matter signals on brain MRI (Wang et al., 2015). (618850)

MalaCards based summary : Hypervalinemia and Hyperleucine-Isoleucinemia, also known as hypervalinemia or hyperleucine-isoleucinemia, is related to hyperleucine-isoleucinemia and maple syrup urine disease. An important gene associated with Hypervalinemia and Hyperleucine-Isoleucinemia is BCAT2 (Branched Chain Amino Acid Transaminase 2), and among its related pathways/superpathways are Glucose / Energy Metabolism and Carbon metabolism. The drugs Insulin, Globin Zinc and insulin have been mentioned in the context of this disorder. Affiliated tissues include brain.
