The other locus, containing the UDP-GlcNAc:betaGal beta-1,3-N-acetylglucosaminyltransferase 2 gene (B3GNT2) and transmembrane protein 17 gene (TMEM17), is ~ 200 kb from the Eps15 homology domain binding protein 1 locus (EHBP1) that has been identified of genome-wide significance in our study on low T1D GRS patients21. The gene discussed is B3GNT2; the disease is type 1 diabetes mellitus.
