Abstract
Abstract HLA antigens (A, B, C and DR loci), serum islet cell antibodies, thyrogastric antibodies, and insulin antibodies were studied in 77 families (25 simplex, 42 multiplex, and 10 multigenerational). In order to test for intrafamilial constancy and intergroup variation, we compared simplex with multiplex families, HLA identical and non identical siblings within families, as well as groups of families characterized by different DR alleles (DR3, DR4, and DR3 DR4) for various immunologic and clinical characteristics. These comparisons did not reveal all the distinct subgroups suggested by different cross-sectional population studies, but did provide evidence for a compoud form having an aggregation of different high risk alleles. This study suggests that in many cases (and possibly especially in families with mutiple affected individuals), there are several different genetic influences leading to IDDM.
