高等医学院校教材《医用生物学》第二版(以下简称《教材》),第149页载:“在有的家系中,甲膑综合征的致病基因(NPa)与基因Ia相连锁,即基因NPa和基因Ia是位于同一条染色体上,基因NPa和基因Ib或i则不在同一条染色体上。因此可以预测一个婴儿只要有A型血,一般必将患甲膑综合征。”笔者认为,“一个婴儿只要有A型血,一般必将患甲膑综合征”的诊断结果是片面的、错误的,而其前提条件是很欠缺的、笼统的。显性遗传病甲膑综合征患者的基因型是杂合型 Medical School of Medical Sciences, Second Edition (“Textbook”), p.149: “In some pedigrees, the causative gene of cajal syndrome (NPa) is linked to gene Ia, Namely gene NPa and gene Ia are located in the same chromosome, gene NPa and gene Ib or i are not in the same chromosome .Therefore, it can be predicted that as long as a baby with blood type A, the general will be suffering from nail syndrome. ”In my opinion , “A baby with blood type A, the general will be suffering from nail syndrome,” the diagnosis is one-sided, wrong, and its preconditions are lacking, general. The genotype of Dominant Syndrome patients with formagalopathies is heterozygous
