    Summary
    Enables 7-dehydrocholesterol reductase activity. Acts upstream of or within several processes, including blood vessel development; lung epithelial cell differentiation; and sterol biosynthetic process. Predicted to be located in endoplasmic reticulum and nuclear outer membrane. Predicted to be active in endoplasmic reticulum membrane. Is expressed in adrenal gland; genitourinary system; and neural retina. Used to study Smith-Lemli-Opitz syndrome. Human ortholog(s) of this gene implicated in Behcet's disease and Smith-Lemli-Opitz syndrome. Orthologous to human DHCR7 (7-dehydrocholesterol reductase).

    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.
