The aim of this study is to investigate … WebOn an average, CYP3A5 is expressed at 20-fold lower levels than CYP3A4 in individuals who express this CYP isoform and harbor the CYP3A5∗1 allele. Nonexpression of CYP3A5 is commonly caused by genetic polymorphisms that produce aberrant splicing and truncated protein (CYP3A5∗3, CYP3A5∗6) (Kuehl et al., 2001).
