We demonstrate, by plotting the deviations from expected ratios of identity by descent (IBD) scores of sibling pairs having only one affected individual, that simplex pairs can, under certain constraints, provide a rich source of information concerning linkage relationships of a disease susceptibility gene. In addition, two statistical tests of significance are presented, one for a fixed sample size and a second for a sequential sampling approach.
通过绘制仅有一个患病个体的同胞对的亲缘系数(IBD)得分与预期比例的偏差,我们证明,在一定限制条件下,单患病同胞对可为疾病易感基因的连锁关系提供丰富的信息来源。此外,还提出了两种显著性统计检验方法,一种用于固定样本量,另一种用于序贯抽样方法。
