CYP7A1 is not associated with a relevant phenotype in OMIM or Gene2Phenotype. PMID: 9802883 describes a patient with severe cholestasis, cirrhosis, and liver synthetic failure and variants were found in CYP7B1. There were no variants found in CYP7A1. CYP7A1 is associated with Hypercholesterolemia on Orphanet.
Therefore, this gene should be demoted from Green to Red.Created: 29 Oct 2020, 3:27 p.m. | Last Modified: 29 Oct 2020, 3:27 p.m.
