Next‐generation targeted sequencing (NGTS) of HLA‐DRB3, DRB4, DRB5, DRB1, DQA1, DQB1, DPA1, and DPB1 alleles from DNA collected from 68 T1D, 219 CD, and seven T1D w/CD patients were compared with 636 HLA‐genotyped Swedish children from the general population selected as controls. Here, HLA-DRB1 is linked to type 1 diabetes mellitus.
