rs776746, also known as 6986A>G, is a SNP encoding the (nonfunctional) CYP3A5*3 allele of the CYP3A5 gene.
CYP3A5*3 has been studied especially in connection with the metabolism of tacrolimus, an immunosuppressive drug used in organ transplantation. The optimal therapeutic dose is in a relatively narrow window, so blood concentration monitoring is recommended. CYP3A5*3 carriers tend to build up higher levels of tacrolimus than CYP3A5*1 carriers, unless their tacrolimus intake is reduced.
