In parallel to the results of our analysis in sarcoidosis and its Stages I, II, and III, no copy number variation of FCGR3B gene has been observed by some researchers in SLE, RA, anti-neutrophil cytoplasmic antibody-associated vasculitis (AASV), primary Sjögren’s syndrome (pSS), Addison’s disease, Grave’s disease and anti-glomerular basement membrane antibody disease (anti-GBM disease) [16,18,23–26]. Here, FCGR3B is linked to peeling skin syndrome.
