1特发性少精子症和无精子症与Pygo2基因蛋白编码区SNPs的相关性显示文摘男性不育常伴随精子数量减少。Pygo2基因在染色质重塑的伸长精细胞中表达,其功能受损会导致精子形成阻滞和精子生成减少而引发不育。文章旨在检测引起人特发性少精子症和无精子症的Pygo2基因突变。从77例正常生育力男性和195例特发性少精子症和无精子症患者静脉血提取DNA,采用聚合酶链式反应-测序方法对Pygo2基因3个蛋白质编码区进行测序对比,非同义单核苷酸多态性(Single nucleotide polymorphisms,SNPs)位点分别用SIFT、Polyphen-2和Mutation Taster软件进行诱发蛋白质结构和表型改变的检测和分析。结果表明,195例患者中,178例(30例轻度或中度少精子症,57例重度少精子症和91例无精子症)基因序列分析报告完好,无精子症中3例患者分别在2个位点(rs61758740,rs141722381)发生了非同义突变SNPs,重度少精子症中1例患者在位点rs61758741发生了非同义突变,3个突变位点在SNPs基因数据库都已有报道,轻度或中度少精子症患者以及正常生育力男性中不存在SNPs。rs61758740可使PYGO2蛋白第141位蛋氨酸(M)变为异亮氨酸(I),rs61758741使PYGO2蛋白第261位碱性赖氨酸(K)变为酸性谷氨酸(E),rs141722381使PYGO2蛋白第240位亲水侧链天冬酰胺(N)变为疏水侧链异亮氨酸(I)。软件分析表明,在所发现的3个SNP非同义突变位点中,rs141722381引起的单个氨基酸改变会导致PYGO2蛋白空间结构破坏和诱发相关疾病。因此,Pygo2基因蛋白质编码序列区SNPs可能是特发性少精子症和无精子症的诱发因素之一,导致男性不育。葛少钦 Jeanine Grifin 刘丽华 Kenneth I.Aston Luke Simon Timothy G.Jenkins Benjamin R.Emery Douglas T.Carrell 2013遗传2013,35,5:6
