Abstract

The genes associated with Sjögren syndrome (SS) can be assigned to the NF-kB pathway, the IFN signaling pathway, lymphocyte signaling, and antigen presentation. The frequencies of risk variants show they are common with modest genetic effects. The strongest genetic association outside the human leukocyte antigen region is in IRF5, a gene relevant in the IFN signaling pathway and for B cell differentiation. Although no association has been found with the NF-kB gene itself, associations in TNFAIP3 and TNIP1 (both genome-wide significant), VCAM1 and IRAK1BP (both suggestive), point to genetic explanations for dysregulation of the NF-kB pathway in SS.
