Gene Gene information from NCBI Gene database.
Entrez ID 5828
Gene name Peroxisomal biogenesis factor 2
Gene symbol PEX2
Synonyms (NCBI Gene)
PAF1PBD5APBD5BPMP3PMP35PXMP3RNF72ZWS3
Chromosome 8
Chromosome location 8q21.13
Summary This gene encodes an integral peroxisomal membrane protein required for peroxisome biogenesis. The protein is thought to be involved in peroxisomal matrix protein import. Mutations in this gene result in one form of Zellweger syndrome and infantile Refsum
