Genes affected

ACOX2 (HGNC:120): (acyl-CoA oxidase 2) The product of this gene belongs to the acyl-CoA oxidase family. It encodes the branched-chain acyl-CoA oxidase which is involved in the degradation of long branched fatty acids and bile acid intermediates in peroxisomes. Deficiency of this enzyme results in the accumulation of branched fatty acids and bile acid intermediates, and may lead to Zellweger syndrome, severe cognitive disability, and death in children.

ACOX2 Gene-Disease associations (from GenCC):

• congenital bile acid synthesis defect 6
