A Taiwanese study describes four patients with neutralizing anti-IFNγ auto-antibodies, all of whom developed NTM disease and three of whom developed Salmonella-related infections (besides two with systemic Talaromyces marneffei infection, one patient with pulmonary TB, one with Legionella pneumonia, one with herpes zoster, one with oral herpes simplex and one with Epstein–Barr virus (EBV) associated disease) [63]. This evidence concerns the gene IFNG and herpes zoster.
