Abstract

The marker-association-segregation-chi 2 (MASC) method with consideration of age, for nonaffected persons, and of age at onset, for affected persons, was applied to a sample of 308 HLA-typed families. Hazard rates modeling the instantaneous risk of catching the disease were estimated under the exponential distribution and with satisfactory goodness of fit. This class of models shows that the hypothesis of the absence of parental imprinting cannot be rejected for insulin-dependent diabetes mellitus.

摘要

将考虑年龄(针对未患病个体)和发病年龄(针对患病个体)的标记关联分离卡方(MASC)方法应用于308个进行了HLA分型的家庭样本。在指数分布下估计了模拟患病瞬时风险的风险率,拟合优度良好。这类模型表明,胰岛素依赖型糖尿病不存在亲本印记的假设不能被拒绝。
