Title: Loss of Sc5d results in micrognathia due to a failure in osteoblast differentiation.
Data, including data from studies in heterozygotic transgenic/knockout mice, suggest that Sc5d plays essential role in ultraviolet radiation-induced vitamin D3 synthesis in keratinocytes/skin. Homozygotic deletion of Sc5d is lethal in utero.

Data suggest that although cholesterol synthesis is impaired in both Dhcr7 mutant and Sc5d(-/-) embryonic brain, synthesis of nonsterol isoprenoids may be increased and thus contribute to Smith-Lemli-Opitz syndrome and lathosterolosis pathology.

There were reduced nuclear levels of the lipogenic transcription factor sterol regulatory element binding protein-1 in MCD-fed mice, but no consistent reduction in fatty acid synthesis genes (acetyl-CoA carboxylase and fatty acid synthase).

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.
