Long-Chain 3-Hydroxyacyl-Coa Dehydrogenase Deficiency, also known as lchad deficiency, is related to mitochondrial trifunctional protein deficiency 1 and abdominal obesity-metabolic syndrome 1, and has symptoms including myalgia and weakness. An important gene associated with Long-Chain 3-Hydroxyacyl-Coa Dehydrogenase Deficiency is HADHA (Hydroxyacyl-CoA Dehydrogenase Trifunctional Multienzyme Complex Subunit Alpha), and among its related pathways/superpathways are Metabolism and Fatty acid metabolism. The drugs Glycerin and (3-Carboxy-2-(R)-Hydroxy-Propyl)-Trimethyl-Ammonium have been mentioned in the context of this disorder. Affiliated tissues include liver and eye, and related phenotypes are photophobia and hypoglycemia
