Among the 9 shared genes (HEMK1, GSDMB, ERAP1, PPIP5K2, TMEM69, DNLZ, SDCCAG3, CARD9, and PLEKHA1), two of them, GSDMB (gasdermin B) and PLEKHA1 (pleckstrin homology domain-containing family A member 1) were previously identified as candidate genes for T1D (Morris et al., 2012) and T2D (Mahajan et al., 2018), respectively. The gene discussed is ERAP1; the disease is type 1 diabetes mellitus.
