Molecular assay reagents intended to identify mutations in the hydroxyacyl-Coenzyme A dehydrogenase/3-ketoacyl-Coenzyme A thiolase/enoyl-Coenzyme A hydratase (trifunctional protein), beta subunit (HADHB) gene, located at chromosome 2p23, which produces beta subunit of mitochondrial trifunctional protein. Mutations at this locus have been identified in patients with long-chain hydroxyacyl-CoA dehydrogenase deficiency (trifunctional protein deficiency, type 2); they are also present in patients with acute fatty liver of pregnancy and with a disease characterized by simultaneous hemolysis, elevated liver enzyme levels, and a low number of platelets (HELLP syndrome).
