目的:研究中国汉族人群中雄激素受体基因(AR)第一外显子上的(CAG)n多态性与男性尿道下裂发病风险的相关性。方法研究对象为342例男性尿道下裂患儿以及351例健康人。从外周血淋巴细胞中提取全基因组DNA,对AR基因上的第一外显子(CAG)n进行PCR扩增,扩增产物以Sanger测序方法对其测序,计算各样本的(CAG)n分布情况。采用卡方检验(Chi-square test)比较病例组与对照组之间的(CAG)n分布,并分析(CAG)n对男性尿道下裂发病风险的影响。结果病例组(CAG)n为15~44,平均长度23.65±3.36;对照组为19~31,平均长度23.14±1.87,两组CAG重复序列有明显统计学差异(P=0.013)。当n≥23,24,25,26时,尿道下裂发病风险分别为1.47(CI:1.081~2.001),1.356(CI:1.004~1.830),1.484(CI:1.063~2.071),1.565(CI:1.034~2.369),各组均有明显统计学意义(P<0.05);而当n≤19时,尿道下裂患病风险为2.111(CI:0.935~4.767),P=0.05。结论 AR基因第一外显子上的(CAG)n与男性尿道下裂发病有明显的相关性,CAG重复序列越长,尿道下裂的发病风险越高。

Objetive To analyze the risk for hypospadias in Han Chinese modified by the CAG repeat polymorphismintheexon1ofAndrogenReceptorgene.Methods DNAwasextractedformperipheralblood samples which came from 342 cases with hypospadias and 351 healthy voluntary anonymous blood sample do-nors.The CAG repeat lengths were amplified with PCR,which were calculated the difference between the hy-pospadiasandcontrolgroupusingChi-squaretest.Results ThemeanlengthofCAGinhypospadiaswas 23.65 ±3.36 (range 1 5 ~44),and it was 23.1 4 ±1 .87 (range 1 9 ~31 )in control group.A significant in-crease of the CAG repeat length in hypospadias group was detected when compared with the controls (P=0.01 3 ).In addition,the odds ratios between the hypospadias and controls revealed that the hypospadias cases are about 1 .5 times to have longer CAG repeats than a shorter length for each repeat length investigated. Con-clusion WehaveinvestigatedalargenumberofhypospadiascaseswithregardstotheCAGrepeatlength,and we provided evidence that a higher number of the CAG repeat sequence in the AR gene have a clear effect on the risk of hypospadias in Han Chinese.
