We prioritized 21 genes (CLNK, EED, LZTFL1, MGAT4A, NAA38, NFKB1, PHACTR4, PHLPP2, PLEKHA1, P2RY12, REST, RGS14, SERPINB6, SESN3, SLC25A29, SPAG1, STIM2, THEMIS, TMEM80, VSIR, ZNF217) that have not been identified in previous T1D genome-wide association studies. Here, SERPINB6 is linked to type 1 diabetes mellitus.
