Conducting the largest T1D GWAS to date allowed us to find four novel signals reaching genome‐wide significance (near RLIMP2, SLC25A37, MAGI3 and LHFPL5), but priorityFDR analysis allowed us to detect additional new signals, all satisfying FDR ≤ 1%, that may also be worthy of follow up. This evidence concerns the gene MAGI3 and type 1 diabetes mellitus.
