However, the rs2230926 variant allele seems to confer a higher risk to develop lymphoma in pSS patients, while in RA patients, the presence of RF resulted significantly associated with the variant allele.
Increased prevalence of the rs2230926 mutant variant was detected in both SS-lymphoma and SS-nonlymphoma subgroups compared to HC (8.8% vs. 7.6% vs. 3.6%, <i>p</i> values: 0.04 and 0.03, respectively) in association with higher IgM, LDH serum levels, and PB <i>Bcl-XL</i> transcripts but lower leucocyte and neutrophil counts.
A germline and coding polymorphism (rs2230926) of TNFAIP3 (A20), a central gatekeeper of nuclear factor-kappa B (NF-kB) activation, was recently found associated with primary Sjögren's syndrome (pSS)-associated lymphoma in a French cohort.We aimed to replicate this association.
The rs2230926 exonic variant was associated with an increased risk for pSS complicated by lymphoma (odds ratio, 3.36 [95% confidence interval, 1.34-8.42], and odds ratio, 3.26 [95% confidence interval, 1.31-8.12], vs controls and pSS patients without lymphoma, respectively; P = .011).
