A disease resembling childhood coeliac disease occurred in one of identical twins. When the twins were investigated at the age of 23 the initial diagnosis could not be substantiated but the twin who had been ill had selective IgA deficiency. Differences dating from early infancy may have been a result of the discordance for IgA deficiency. Thus in some patients environmental influences may be important in either the initiation or the perpetuation of the deficiency.

一对同卵双胞胎中的一人患上了一种类似儿童乳糜泻的疾病。这对双胞胎在23岁时接受检查，最初的诊断无法得到证实，但患病的双胞胎患有选择性IgA缺乏症。早在婴儿期就存在的差异可能是IgA缺乏不一致的结果。因此，在一些患者中，环境影响可能在该缺乏症的起始或持续过程中起重要作用。
