Detection the Genetic Variation for GSTM1, GSTT1 Genes in Smokers by Multiplex-PCR Technique

Abstract

In this study, Multiplex-PCR technique were used to detect the loss of GSTT1, GSTM1, and the effect of some of the Hb level on smokers. A total of 103 blood samples were collected from smokers in Tikrit and 70 from non-smokers as control groups. The results showed a significant increase in PCV, Hb compared with non-smokers, and the presence or absence of genes (GSTT1, GSTM1) was detected. In all samples compared with control using Multiplex-PCR markers, The highest percentage genotype that lost the two genes GSTM1, GSTT1 was (55% ), Followed by 23% for the genotype lost of the gene GSTM1, and the genotype lost of the gene GSTT1 (15%). The natural genotype the genes was the lowest (7%). The non-smokers group was the highest proportion of the natural genotype (35.71%), followed by the genotype lost of the gene GSTT1 (25.71%), the genotype lost of the gene GSTM1 (7%) and the genotype lost of the gene GSTT1 GSTM1. One of the results of the distribution of gene loss in smokers was the highest percentage of the genotype lost GSTM1, GSTT1 For smokers of cigarettes and Argile reached 75%, respectively, followed by GSTT1, the highest percentage of smokers (20%). The GSTM1 was the highest (30%). The results indicate that the genotypes missing of one or both genes have a significant impact on human health and loss, which may cause an increase in the risk of some diseases, the most important of which is heart disease due to the loss of enzymes that coding those genes. .
