BACKGROUND: The CYP2D6 gene locus is complex and highly polymorphic. Given the clinical importance of the CYP2D6 enzyme in liver xenobiotic metabolism, genotyping its significant alleles among different ethnic groups is essential for evaluating the efficacy of certain drugs. In this study, we assessed the frequency of the CYP2D6*4, *9, *10, and *41 alleles in a healthy population from northwestern Iran. METHODS: Fifty unrelated healthy individuals from West Azerbaijan Province, Iran, were studied using PCR-RFLP and ARMS-PCR techniques. RESULTS: CYP2D6*9 (rs5030656) allele was not detected. The frequency (%) of CYP2D6*4 (rs3892097), CYP2D6*10 (rs1065852) and CYP2D6*41 (rs28371725) alleles were 10%, 13% and 8%, respectively. CONCLUSION: Our findings indicate that the frequencies of “non-functional” and “reduced function” alleles are relatively high in this population. Determining Cytochrome P450 2D6 allele variations can contribute to risk assessment and patient management regarding adverse or poor drug responses, ultimately aiding in the prevention of increased mortality risks among different populations.
