Allelic frequency of PON1 Q192R, CYP2C19*2 and CYP2C19*17 among Jordanian patients taking clopidogrel
Abstract
Methods: Polymorphisms in CYP2C19 were assessed among 148 patients using PCR-RFLP assay.
Results: The CYP2C19*2, CYP2C19*17, and PON1 Q192R allele frequencies were 9.8, 28.72 and 28.7 %, respectively. On the genotyping side, the frequencies of CYP2C19*1/1* and CYP2C19*1/2* were 80.4 and 19.6 %, respectively, but none of the patients had CYP2C19*2/2* genotype. The genotype frequencies CYP2C19*17 were 47.97, 46.62 and 5.41 % for wild-type C-C, heterozygote C-T, and the mutant T-T, respectively. PON1 genotype was 42.7 % for QQ, and 57.8 % for QR. None of the patients had RR genotype.
Conclusion: Relative to other populations, the observed allelic frequencies are consistent with the values reported for Caucasian and Middle Eastern populations.
