Abstract excerpt
Levels of insulin autoantibodies (IAA) vary among different first degree relatives of insulin-dependent diabetes mellitus patients, suggesting genetic regulation. We previously reported elevated IAA among DR4-positive at risk relatives. In this study, 72/82 at risk relatives were IAA positive, of whom 75% (54/72) carried DR4 versus 20% (2/10) of IAA-negative relatives (P = 0.0004). However, 69% (18/26) of...
