Abstract excerpt
DQA1, DQA2, DQB1, and DRB1 alleles have been determined and the DQA1 and DQB1 DNA gene sequences assigned by using restriction fragment length polymorphisms in 67 diabetic individuals and 72 controls. It has been found that: 1) DQA2 (U allele) is not a susceptibility factor, 2) non-aspartic acid homozygosity in residue 57 (Asp 57 negative) of the DQ beta chains is positively correlated with insulin-dependent...
