Association of ICAM-1 gene variant rs5498 (1462A>G) with non-obstructive azoospermia



Association of ICAM-1 gene variant rs5498 (1462A>G) with non-obstructive azoospermia



Human Fertility 2019: 1-5



The blood testicular barrier (BTB) is a barrier protecting the testes from damage. It also plays an important role in spermatogenesis. The intracellular adhesion molecule-1 (ICAM-1) is a member of the immunoglobulin cell adhesion molecule family and is a constituent component of the BTB. This study was carried out to investigate the association between the single nucleotide polymorphism (SNP) rs5498 in the ICAM-1 gene and non-obstructive azoospermia. A total of 100 male patients with non-obstructive azoospermia and 100 fertile males (healthy control) were included in this study. Genotyping of ICAM-1 gene rs5498 was performed using polymerase chain reaction-restriction enzyme fragment length polymorphism (PCR-RFLP). Both AG and GG genotypes were significantly more prevalent among the infertile men compared to the control group (p < 0.001). The odds ratio (OR) for the polymorphic allele (G) was 2.4 with 95% confidence interval from 1.38 to 3.19 (p < 0.001). The study shows that ICAM-1 rs5498 (1462A>G) SNP is positively associated with an increased risk for obstructive azoospermia, with the genotype AG heterozygotes showing a significantly higher frequency among infertile men.
