Glucose-6-phosphate dehydrogenase (G6PD) is an enzyme in the pentose phosphate pathway (PPP) that plays an important role in protecting cells from oxidative damage by producing NADPH and reduced glutathione. G6PD deficiency is considered one of the most common genetic disorders present in the X chromosome and is the most common of enzymopathic red blood cell disorder. Angiotensin converting enzyme (ACE) plays an essential role in two physiological systems, one leading to the production of angiotensin II and the other to the degradation of bradykinin. Most studies focused on an insertion/deletion (I/D) polymorphism in intron 16 of the ACE gene as a marker for a functional polymorphism. The a2B-adrenergic receptor gene (a2BAR) is a three-amino acid deletion (12Glu9) polymorphism is located on chromosome 2. (Glu9/Glu9) of this polymorphism has been first time studies in G6PD individuals. We have selected 39 G6PD deficiency male individuals and PCR was carried out with the I/D polymorphisms. ACE I/D polymorphism study was carried out in G6PD individuals and showed strong association with DD genotypes and D alleles OR=39.38, p<0.0001 (95% CI=8.80-176.1) and OR=38.58, p<0.0001 (95% CI=13.21-112.6). Another gene of a2BAR I/D polymorphism study cannot show any association in DD genotype OR-0.6882,p=0.9388 (95% CI=0.2035-2.327) and with D allele OR-0.9614,p=0.9388 (95% CI=0.3482-2.653). Our study shows that G6PD deficiency is showing strong association in DD genotype and D allele of ACE gene and a2BAR gene have not shown any important role and one of the reason could be the low sample size.
