Association of eleven single nucleotide polymorphisms with refractive disorders from Eskisehir,Turkey

AIM:To investigate relationship between refractive errors and eleven single nucleotide polymorphisms(SNPs)in HGF,GC,MFN1,GNB4,and VDR genes in Turkish population.METHODS:A group of 212 participants with myopia(n=91),hyperopia(n=45),and emmetropia(n=76)were investigated in this study.SNPs in HGF,GC,MFN1,GNB4 and VDR genes were studied by Snap Shot technique.RESULTS:The patients in this study consists of 47 female/44 male(age:23.47±4.30)patients with myopia,20 female/25 male(age:31.20±8.02)with hyperopia and 33 female/43 male(age:25.22±6.60)with emmetropia.The genotype distribution of the rs7618348 polymorphism,which was the only statistically significant one between myopia and emmetropia group.The genotype distribution of the rs3819545,rs3735520,rs7041,and rs2239182 polymorphisms,which were statistically significant between hyperopia and emmetropia groups.CONCLUSION:The importance of genetic predisposition to refractive errors with respect to etiology of the disease is revealed.It is known that polymorphism studies may differ because of genetic diversity among populations so larger cohort studies are required in different populations to enlighten the etiology of the refractive errors.
