THR107ILE, ARG296CYS, AND SER486THR; This allelic variant is also known as CYP2D6*17 or CYP2D6(Z). Oscarson et al (Mol Pharmacol 52(6):1034-40, 1997) found that in many black African populations, the capacity for CYP2D6-dependent drug metabolism is generally reduced. A specific variant of the CYP2D6 gene (CYP2D6*17) that carries three functional mutations (T107I, R296C, and S486T) has been found to be present in Zimbabwean subjects with impaired CYP2D6-dependent hydroxylase activity. |

DEL; This allelic variant is also known as CYP2D6*5 and CYP2D6(D). In 1 of 42 poor metabolizer individuals (608902), Gough et al. (Nature 347:773-776, 1990) found homozygous deletion of the CYP2D locus. In a poor metabolizer, Gaedigk et al. (Am J Hum Genet 48:943-950, 1991) identified a homozygous 11.5-kb deletion associated with deletion of the entire CYP2D6 gene and total absence of P4502D6 protein in the liver. |
