FCRL1 and type 1 diabetes mellitus: Two SNPs were nominally associated (P < 0.05) with TPOAb levels in our study: rs879564 near MIR7-3HG (P = 0.0289), previously associated with TPOAb in general population, and rs4971154 inside FCRL1 (P = 0.0236), previously associated with TPOAb in T1D patients (Supplementary Table 2, Supplementary Table 3).
