The LTR13-DQB1 indel was linked to six different DRB1-MTCO3P1 haplotypes (Supplementary Table 4), some of which might be useful for predicting the onset of T1D and/or Addison’s disease in multiple populations (Valdes et al., 2012; Vadva et al., 2019). The gene discussed is HLA-DRB1; the disease is type 1 diabetes mellitus.
