| 目的：探索胆石病家族聚集性及遗传方式。方法：采用遗传流行病学病例对照研究方法：，对 317个家系 ( 138个胆石病先证家系和 179个对照家系 )进行研究。结果：病例组一级亲属总的胆石病患病率为 2.60%,显著高于对照组的 1.29% ( χ2 =4.78，P =0.02 88);分离比为显著低于 0.2 5,不符合单基因遗传疾病的特征;遗传度估算显示,该病一级亲属中,遗传度为2 1.80%,其中男性亲属的遗传度为 36.34%,显著高于女性亲属的 14.15 %。结论：在胆石病的病因中,遗传因素起一定作用,尤其对男性作用更为明显。 |

| Objective：To explore the genetic model of gallstone disease(GD).Methods：A case-control study including 317 pedigrees(138 cases and 179 controls)was conducted.Results：The prevelence of the first-degree relatives in cases was 2.60%,significantly higher than that noticed in controls(1.29%).Segregation analysis showed that GD did not possess the characteristics of monogenic model.Meanwhile the results showed that the heritability of the first-degree relatives was 21.80%,with male 36.34%which was significantly higher than the females(14.15%).Conclusion：This study indicated that the genetic factors played an important role in the occurrence of GD,especially in males. |
