CYP2C8, PTGS-1, 2 gene polymorphisms prevalence associated with sensitivity to non-steroidal anti-inflammatory drugs among North Caucasus ethnic groups

Abstract

Find the prevalence of CYP2C8*3 (rs10509681; rs11572080), PTGS-1 (rs10306135; rs12353214) and PTGS-2 (rs20417) alleles and genotypes in four ethnic groups among Laks, Avars, Dargins and Kumyks. The study involved 400 volunteers from four ethnic groups living in Republic of Dagestan: 100 participants from each group. Carriage of polymorphic markers was determined by reverse transcription polymerase chain reaction. Minor allele frequency of the CYP2C8 (rs10509681) was 5.5% in Avars, 10% in Dargins, Laks and Kumyks 6.5% both; CYP2C8 (rs11572080) was 5.5% in Avars, 9.5% in Dargins, 6.5% in Laks, 8.5% in Kumyks; PTGS-1 (rs10306135) in Avars 10.5%, in Dargins 13.0%, in Laks 9.5% and Kumyks 7.5%; PTGS-1 (rs12353214) in Avars 9.0%, in Dargins 4.5%, in Laks 7.5%, in Kumyks 8.0%; PTGS-2 (rs20417) in Avars 1.0%, in Dargins 2.5%, in Laks 3.5%, in Kumyks 5.0%. There were no significant differences between groups. The study of CYP2C8 and PTGS-1 and 2 gene polymorphisms is promising for predicting the effectiveness and safety of non-steroidal anti-inflammatory drug therapy, due to the high prevalence of these polymorphisms in ethnic groups in the North Caucasus.
