HLA-DQB1

From MEpedia, a crowd-sourced encyclopedia of ME and CFS science and history

HLA-DQB1 is a class II human leukocyte antigen gene.[1] HLA genes help the "immune system distinguish the body's own proteins from proteins made by foreign invaders such as viruses and bacteria".[1][2]

Function[edit | edit source]

HLA associations are considered "hallmarks of autoimmune disease".[3] Different variations in HLA-DQB1 have been linked to celiac disease, narcolepsy, type I diabetes, autoimmune Addison's disease, rosacea and multiple sclerosis.[4]

ME/CFS[edit | edit source]

Lande et al. (2020) found two HLA associations that were more common in people with ME/CFS, with 19.2% of ME/CFS patients carrying one of the two HLA associations identified, compared to 12.2% of the control group.[3] The HLA associations more common in ME/CFS patients were HLA-C*07:04 and HLA-DQB1*03:03.[3] The 426 ME/CFS patients in the study met the Canadian Consensus Criteria for ME/CFS, except for four who met the International Consensus Criteria for ME.[3]

A small Norwegian trial found patients positive for HLA-DQB1*03:03 and/or HLA-C*07:04 were more likely to respond to cyclophosphamide than patients without those alleles, 83 vs. 43%.[5]
