Association of polymorphism in cell death pathway gene FASLG with human male infertility

ObjectiveTo investigate –844C>T single nucleotide polymorphism (SNP) present in the promoter of cell death pathway gene FASLG with male infertile phenotype.MethodsGenotyping for SNP FASLG (rs763110) was done by polymerase chain reaction followed by analysis with specific endonuclease (PCR-RFLP). DNA sequencing was used to ascertain PCR-RFLP results.ResultsFASLG –844C>T polymorphism, allele and genotype distribution did not differ significantly between patients and controls (OR: 1.03, 95% CI= 0.7638 to 1.3952, P=0.83). Thus SNP-844C>T of the FASLG gene is not associated with male infertility risk in the analyzed patients.ConclusionsHuman male infertility is a complex disorder and thus other genetic or environmental factors may be contributing to the complex etiology, and further study in other region of Indian populations will verify whether it is associated with male infertility risk.
