本文在424例法乐氏四联症(TOF)患者的Ⅰ、Ⅱ、Ⅲ级亲属中调查该病及其它类型先心病(CHD)的患病率,从而初步确定TOF具有家族倾向,遗传方式为多基因遗传。并用Falconer法计算了该病的遗传度。
In this study, the prevalence of CHD and other types of CHD in 424 patients with TOF (Tetrahymenatrism, TOF) was investigated in order to determine the familial tendency of TOF. The genetic pattern was Multi-genetics. Falconer method was used to calculate the heritability of the disease.
