摘要
为探讨先天性心脏病的遗传方式,对375例先天性心脏病进行了遗传流行病学研究,结果显示该病一级亲属患病率为6.9%,遗传度66.13%±1.13%;二级亲属患病率为1.7%,遗传度为38.25±8.3%,一、二级亲属加权平均遗传度为65.65±1.09%,遗传因素较为重要。在各级亲属患病中,患病率依次为一级亲属(6.9%)、二级亲属(1.7%)、一般群体(0.86%)。所以该病基本符合多基因遗传方式。
In order to explore the genetic model of congenital heart disease (CHD),375 individuals of CHD were investigated.The results showed that the incidence of primary relatives was 6.9% , the heritability was 66.13 ±1.13%, the incidence of secondary relatives was 1.7% and the heritability was 38.25±8.3% respectively.The average heritability among primary,secondary relatives was 65.65±1.09% which suggested that the genetic factor played an important role in pathogenesis. The sequence of the incidence in the relatives showed:primary relatives (6.9%)> secondary relatives (1.7%)> distant relatives (0.86%) and was in accordance with polygenic incidence,suqqesting that gene play an important role in the liability variation of CHD.
