We report two families selected from 124 genotyped Caucasian insulin-dependent diabetes mellitus (IDDM) families because of unusual features. In both families, all offspring are affected and four out of six bear the allele HLA-DR2 which is an uncommon phenotype among diabetic patients. Onset before the age of 1 year in all the patients of one family, association with optic atrophy in the other, and the existence of pairs of affected sibs of different HLA types in both, are infrequent findings and support the evidence of heterogeneity in IDDM.
我们报告了从124个已进行基因分型的白种人胰岛素依赖型糖尿病(IDDM)家庭中挑选出的两个家庭,原因是它们具有不同寻常的特征。在这两个家庭中,所有后代均患病,并且六个中有四个携带HLA - DR2等位基因,这在糖尿病患者中是一种不常见的表型。其中一个家庭的所有患者发病年龄均在1岁之前,另一个家庭的患者伴有视神经萎缩,而且两个家庭中都存在不同HLA类型的患病同胞对,这些都是罕见的发现,并支持了IDDM存在异质性的证据。
