We analysed the polymorphisms at rs78202224 (C/A) for HSF1 gene, rs139496713 (C/T) and rs45504694 (C/A) for HSF2 gene and rs116868327 (G/A) for UBE2I gene in 547 infertile cases (non-obstructive azoospermia = 464, asthenozoospermia = 83) and 419 proven fertile controls of similar age group and ethnicity. SNP genotyping was done using AgenaMassARRY platform (Agena Bioscience, CA). Common, heterozygous, rare genotypes and allelic frequencies were analysed using dominant, recessive and co-dominant models. Data shows no significant association between HSF1, HSF2 polymorphisms and male infertility. However, under dominant (GG vs GA+AA) and co-dominanat (GG vs GA) model, polymorphism at the rs116868327 (G/A) locus in UBE2I gene was found to be linked with asthenozoospermia in males with a significant odd-ratio of 6.91 (confidence interval at 95% was 1.52-31.46; p=0.017). Moreover, frequency of rare allele was higher (2.4%) compared to controls (0.4%). Thus, this data showed a significant risk of developing asthenozoospermic condition in males (Odds ratio= 6.75; Confidence interval at 95%= 1.50-30.49; P= 0.018]. Hence, more number of genotyping studies along with the functional assay in multiple cohorts is needed to validate potential variants associated with male infertility.
我们分析了547例不育病例(非梗阻性无精子症=464例,弱精子症=83例)和419例年龄和种族相似的已证实有生育能力的对照者中,热休克因子1(HSF1)基因rs78202224位点(C/A)、热休克因子2(HSF2)基因rs139496713位点(C/T)和rs45504694位点(C/A)以及泛素缀合酶E2I(UBE2I)基因rs116868327位点(G/A)的多态性。使用AgenaMassARRY平台(Agena Bioscience公司,加利福尼亚州)进行单核苷酸多态性(SNP)基因分型。采用显性、隐性和共显性模型分析常见、杂合、罕见基因型和等位基因频率。数据显示HSF1、HSF2多态性与男性不育之间无显著关联。然而,在显性模型(GG与GA+AA)和共显性模型(GG与GA)下,发现UBE2I基因rs116868327位点(G/A)的多态性与男性弱精子症相关,显著优势比为6.91(95%置信区间为1.52 - 31.46;p = 0.017)。此外,罕见等位基因的频率(2.4%)高于对照者(0.4%)。因此,该数据显示男性患弱精子症的风险显著(优势比= 6.75;95%置信区间= 1.50 - 30.49;P = 0.018)。因此,需要更多的基因分型研究以及多个队列中的功能测定来验证与男性不育相关的潜在变异。
