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.
Genotyping of the most common coding polymorphism, rs2230926, in the MADGC collection and additional control individuals revealed a significant association with Sjögren's syndrome (OR=3.38, P=0.038), Crohn's disease (OR=2.25, P=0.041), psoriasis (OR=0.037, P=0.036) and RA (OR=1.9, P=0.025).
