MTCO3P1 and chronic primary adrenal insufficiency: Some of the MTCO3P1 alleles together with dimorphic haplotypic TE markers such as the LTR13-DQB1, AluMT2, AluMT3, and the 7-kb #44 indel might be useful genomic markers for subdividing MHC class II haplotype disease associations into different categories, such as the HLA-DRB1∗03/DQA1∗03/DQB1∗03 haplotypes associated with TID and/or autoimmune Addison’s disease (Table 2, Pani et al., 2002; Gambelunghe et al., 2005).
