PEX16 (Peroxisomal Biogenesis Factor 16) is a Protein Coding gene. Diseases associated with PEX16 include Peroxisome Biogenesis Disorder 8B and Peroxisome Biogenesis Disorder 8A. Among its related pathways are Peroxisome. The protein encoded by PEX16 is an integral peroxisomal membrane protein. An inactivating nonsense mutation localized to this gene was observed in a patient with Zellweger syndrome of the complementation group CGD/CG9. Expression of PEX16 product morphologically and biochemically restores the formation of new peroxisomes, suggesting a role in peroxisome organization and biogenesis. Alternative splicing has been observed for PEX16 and two variants have been described.
