Fabris et al. (2015) also reported ZnT8 as a complement to the current T1D autoantibodies (GADA, IA-2A, IAA, and ICA) in a large paediatric Italian population; 49.8% of the patients with T1D were found to be ZnT8 autoantibody positive, confirming ZnT8A as an important additional independent diagnostic marker [24]. Here, SLC30A8 is linked to type 1 diabetes mellitus.
