    Summary
    This gene is a member of the cytochrome P450 gene superfamily. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This gene is a segregating pseudogene, where some individuals may have an allele that encodes a functional enzyme, while other individuals have an allele encoding a protein that is predicted to be non-functional. In this case, the functional allele is thought to be rare. This locus is part of a cluster of cytochrome P450 genes on chromosome 22. [provided by RefSeq, Jan 2017]

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

      Description
      Transcript Variant: This variant (2, noncoding) uses an alternate splice site resulting in a longer transcript compared to variant 1. This noncoding variant represents the reference genome allele, which does not encode a full-length protein and is predicted to be non-functional.
