Aim: To determine islet autoantibody profiles at time of seroconversion and track changes in antibody profiles on follow-up (1–2 years after seroconversion) with respect to age at first antibody appearance, genetic predisposition and rate of progression to type 1 diabetes (T1D). Methods: Islet autoantibodies (IAA, GADA, IA-2A, IA-2βA, ZnT8A) were measured in follow-up serum samples of 142 confirmed autoantibody-positive children from the BABYDIAB study (median follow-up from birth 11.7 years). Antibody binding to epitope regions on GAD65 (NH2, MID, COOH) and IA-2 (JM, PTP), polymorphic variants of ZnT8 (R325, W3…
