Polymorphisms in the CYP2E1 and GSTM1 genes as possible protection factors for leprosy patients.

BACKGROUND: The CYP2E1 and GSTM1 genes encode metabolic enzymes that have key functions in drug modification and elimination. METHODOLOGY/PRINCIPAL FINDINGS: We investigated the possible effects of CYP2E1 and GSTM1 polymorphisms in 71 leprosy patients and in 110 individuals from the general populati...

description BACKGROUND: The CYP2E1 and GSTM1 genes encode metabolic enzymes that have key functions in drug modification and elimination. METHODOLOGY/PRINCIPAL FINDINGS: We investigated the possible effects of CYP2E1 and GSTM1 polymorphisms in 71 leprosy patients and in 110 individuals from the general population. The GSTM1*0 null allele and INDEL CYP2E1*1D mutant genotypes were analyzed by conventional PCR, while CYP2E1 SNPs (1053C>T, 1293G>C and 7632T>A) were determined by RT-PCR. In leprosy patients, the GSTM1*0 and CYP2E1*5 alleles and the combined alleles GSTM1*0/CYP2E1*6 and GSTM1*0/CYP2E1*5 were significantly related to a baciloscopic index (BI) (BI<3), while the CYP2E1*6 allele was related to a better clinical evolution in the leprosy spectrum. CONCLUSIONS/SIGNIFICANCE: Therefore, GSTM1*0, CYP2E1*5 and CYP2E1*6 may be possible protection factors for leprosy patients.
