Genotyping assay to predict CYP3A5 phenotype (SJ-01-0005)

St. Jude Reference #SJ-01-0005

Description

CYP3A5 is an important contributor in drug clearance and involved in regulating the levels of endogenous paracrine or endocrine factors in certain organs such as the kidneys. Two single nucleotide polymorphisms found in CYP3A5 have been identified that result in splice variants, which contribute to decreased levels of CYP3A5 protein. A diagnostic assay detecting these mutations would be an important tool in identifying appropriate therapeutic treatments for individual patients.
