| Identified Mutation |
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. |
| Remarks |
Donor subject is heterozygous for a variant CYP2D6 gene (CYP2D6*17) which contains three amino acid substitutions: a C>T mutation at nucleotide 1111 resulting in thr107-to-ile substitution [Thr107Ile (T107I)] , a C>T transition at nucleotide 2938 in exon 6 resulting in an arg296-to-cys [Arg296Cys (R296C)] and a G>C transversion at nucleotide 4268 in exon 9 resulting in a ser486-to-thr [Ser486Thr (S486T)] |
