Association of single nucleotide polymorphisms of PATZ1 gene with azoospermia / 中华医学遗传学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the relationship between the polymorphisms of single nucleotide polymorphisms(SNPs) in rs2240424, rs2057951, rs2240427 and rs714909 loci in the PATZ1 gene and azoospermia.</p><p><b>METHODS</b>The allele and genotype frequencies of the four SNPs were investigated in 180 patients with azoospermia and 190 normal men as controls by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) analysis. The allele and genotype frequencies of the four SNPs were investigated in 180 patients with azoospermia and 190 normal men as controls by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) analysis.</p><p><b>RESULTS</b>The frequencies of allele C (35.0% vs. 27.6%, P=0.031) and individuals with allele C (TC+CC) (57.8% vs. 46.3%, P=0.027) at the rs2057951 locus in azoospermic patients were significantly higher than that in normal men. There was a significant difference in distribution of haplotypes of the four SNPs between the two groups (P=0.01). Hapoltypes ACAC (11.1% vs. 6.6%, P=0.029) and ACGC (11.2% vs. 5.2%, P=0.003) increased significantly in azoospermic patients compared with controls.</p><p><b>CONCLUSION</b>The allele C of rs2057951 locus and haplotypes ACAC and ACGC of the four SNPs in PTAZ1 gene increased the susceptibility to azoospermia, suggesting that PATZ1gene may be associated with azoospermia.</p>
