title: Autoantibodies and HLA susceptibility markers in Canadian first-degree relatives of patients with type 1 diabetes.
abstract: We examined the frequencies of autoantibodies to glutamate decarboxylase, GAD65, protein tyrosine phosphatase, IA-2/ICA512, and insulin, and of HLA class II markers in ICA-positive first-degree relatives of patients with type 1 diabetes. Our results indicate that while the presence of HLA susceptibility markers is associated with anti-islet autoantibodies, protective DQB1 markers do not absolutely prevent development of autoantibodies or progression to autoimmune diabetes.
