عنوان انگلیسی Association of Single Nucleotide Polymorphisms in the PYGO2 and PRDM9 Genes with Idiopathic Azoospermia in Iranian Infertile Male Patients
چکیده انگلیسی مقاله Background: Azoospermia is a risk factor for infertility affecting approximately 1% of the male population. Genetic factors are associated with non-obstructive azoospermia (NOA). Pygo2 and PRDM9 genes are involved in the spermatogenesis process. The present study aimed to assess the association of single nucleotide polymorphism (SNP) in the Pygo2 (rs61758740 and rs61758741) and PRDM9 (rs2973631 and rs1874165) genes with idiopathic azoospermia (IA).Methods: A cross-sectional study was conducted from October 2018 to August 2019 at Rooya Infertility Centre (Qom, Iran). A total of 100 infertile patients with NOA and 100 men with normal fertility were enrolled in the study. Tetra-primer amplification refractory mutation system-PCR method was used to detect SNPs rs61758740, rs61758741, and rs2973631. The restriction fragment length polymorphism method was used for SNP rs1874165. In addition, luteinizing, follicle-stimulating, and testosterone hormone levels were measured. Results: The results showed a significant increase in luteinizing and follicle-stimulating hormone levels in the patient group (P< 0.001), but a non-significant difference in testosterone levels in both groups. SNP rs61758740 (T>C) was associated with the increased risk of azoospermia (OR: 2.359, 95% Cl: 1.192-4.666, P=0.012). SNP rs2973631 showed a significant difference in genotype frequency between the patient and control groups in the dominant, recessive, and codominant models. However, in the case of SNP rs1874165, the difference was significant in the dominant, codominant, and overdominant models. Conclusion: There is an association between azoospermia and SNPs in Pygo2 and PRDM9 genes in Iranian infertile male patients with IA. SNPs can be considered a risk factor for male infertility. It should be noted that this article was published in preprint form on the website of europepmc (https://europepmc.org/article/ppr/ppr416800).
