Allelic and genotype frequencies of catechol-O-methyltransferase (Val158Met) and CYP2D6*10 (Pro34Ser) single nucleotide polymorphisms in the Philippines.

ABSTRACT: A hospital-based cross-sectional study was conducted to determine the allelic and genotype frequencies in the genes encoding for catechol-O-methyltransferase and CYP2D6*10 among healthy volunteers and patients clinically diagnosed with cancer pain. PCR-RFLP was used to identify COMT and CYP2D6*10 genotypes. Allelic frequencies among healthy volunteer Filipinos were 0.83 and 0.17 for the COMT Val and COMT Met alleles, respectively. Calculated frequencies in Hardy-Weinberg equilibrium (HWE) were 73% for COMT Val/Val, 26% for COMT Val/Met, and 1% for COMT Met/Met genotype. For CYP2D6*10, allelic frequencies in HWE among volunteers were 0.46 for the C allele and 0.54 for the T allele. Twenty percent were identified as homozygous for the wild-type C/C genotype, 56% were identified as heterozygo
