Variable drug metabolism genes in Arab population
Copyright policy )Variable drug metabolism genes in Arab population
Cataloging interethnic differences in the distribution of genotypes of drug metabolic genes provides valuable information for profiling the pharmacogenetics of a population. We used PCR analysis to catalog the frequencies of alleles and genotypes for CYP1A1, NAT2, GSTs, MTHFR, MTR (MS) and NQO*1 in Arabs. The frequencies of alleles and/or genotypes for CYP1A1*2A, GSTT1 null, GSTT1 and GSTM1 double null, and GSTP1 A1578G in Arabs were significantly higher than those reported in Caucasians. However, the distribution of NAT2 acetylator phenotypes in both populations was similar. In contrast, the frequencies of MTHFR 677T allele and the combined (677+1298) genotypes for low activity were lower than those reported in Caucasians. Other alleles in Arabs, including CYP1A1 T3801C and GSTP1 A1578G were present in frequencies similar to Africans. The overall profile of variations in metabolism genes in Arabs is thus unique.
