Accelerated progression to Type 1 diabetes in the presence of HLA-A*24 and -B*18 is restricted to multiple-islet autoantibody-positive individuals with distinct HLA-DQ- and autoantibody risk profiles Vrije Universiteit Brussel KU Leuven
OBJECTIVE: We investigated the effect of HLA class I risk alleles on disease progression in various phases of subclinical islet autoimmunity in first-degree relatives of patients with type 1 diabetes. RESEARCH DESIGN AND METHODS: A registry-based group of siblings/offspring (aged 0-39 years) was monitored from single- to multiple-autoantibody positivity (n = 267) and from multiple-autoantibody positivity to clinical onset (n = 252) according ...
