The autoimmune disease risk variant NCF1-His90 is associated with a reduced risk of tuberculosis in women by Xinjun Hu, Shasha Li, Renliang Huang, Ziwei Fu, Chenyu Ma, Zheng Cheng, Hongjun Hu, Qiaomiao Zhou, Frank Petersen, Xinhua Yu, Xinhua Yu, Junfeng Zheng

“…This casual variant confers an increased risk for multiple autoimmune disorders, including primary Sjögren’s syndrome and systemic lupus erythematosus. Given the high prevalence of this autoimmune disease risk variant in East Asia, we hypothesized that it may confer an evolutionary advantage by providing protection against infectious diseases.MethodsTo test this hypothesis, we investigated whether the NCF1 rs201802880 variant offers a protective effect against tuberculosis (TB), a historically significant and deadly infectious disease. …”
