Indeed, our analysis identified a number of genes common to all three datasets that have been previously demonstrated to play important roles in pSS pathogenesis including several members of the CXC chemokine family of cytokines including CXCL9, CXCL10, CXCL11, CXCL13 (15, 51, 52), members of the guanylate-binding protein family; GBP1, GBP5 (49, 53, 54), as well as AIM2 (55), CD52 (56), and GZMK (57). The gene discussed is CXCL9; the disease is peeling skin syndrome.
