DDR1 and type 1 diabetes mellitus: Notably, increased expression was observed for the symbol genes BTN2A2, BTN3A1, FLOT1, DDR1, HLA-DQA2, HLA-DQB2, HLA-DRB5, HLA-DQA1, and HLA-DPA1. For HIC and T1D (Supplementary Table S15), we identified 1 SNP (rs9262670) associated with the increased expression of HLA-DQA2 and HLA-DQB2 in monocytes, CD4 T cells, CD8 T cells and B cells.
