Genes affected

HACL1 (HGNC:17856): (2-hydroxyacyl-CoA lyase 1) Enables several functions, including 2-hydroxy-3-methylhexadecanoyl-CoA lyase activity; ATP binding activity; and cation binding activity. Involved in fatty acid alpha-oxidation; phytanic acid metabolic process; and protein targeting to peroxisome. Located in nucleoplasm and peroxisome.
