dc.description.abstract | Aim To search for a relationship between ultra-rapid metabolism catalysed by cytochrome P450 2C9 (CYP2C9) and its genotypes. Methods DNA from a Swedish ultra-rapid metaboliser patient [losartan metabolic ratio (MR) <0.13] and three healthy Swedes with normal CYP2C9 activity and a MR of about 1 were assessed for variation in the CYP2C9 gene. Direct DNA sequencing was performed for all exons and exon-intron junctions and also for -2100 bp of the 5'-flanking regions of the CYP2C9 gene. This analysis revealed four intronic mutations [single nucleotide polymorphisms (SNPs) 1-4] in the three samples with normal MR while no variation was observed in the ultra-rapid metaboliser. PCR/restriction fragment length polymorphism and allele-specific PCR methods were subsequently developed to screen 85 Swedes and 128 Koreans without CYP2C9*2 or *3. Results We found a significant relationship between SNP 4 (IVS8-109A>T) and CYP2C9 activity (chi(2)-test, p=0.011) in the Swedes. Twenty Swedes with the lowest MR were compared with 20 Swedes with the highest MR, revealing a strong association (p=0.001) between SNP4 and higher MR. For homozygous SNP 1 (IVS1+83T>C), SNP 2 (IVS2+73T>C), and SNP 3 (IVS6+95A>G), no phenotype and genotype relationships were found, but the MR was generally higher among the Swedes compared to the Koreans (Mann-Whitney test, p<0.05). Conclusions We found that the SNP 4 IVS8-109T allele is associated with a higher CYP2C9 MR in healthy Swedish subjects, but further investigations need to be carried out to establish a molecular explanation for ultra-rapid CYP2C9-catalysed metabolism. Haplotype based on SNPs 1-4 did not seem to contribute to variation in the MR of the Korean subjects nor play a role in determining the MR of the Swedish ones. | - |
