Significantly decreased prevalence of rs11797 A minor allele was detected in SS patients complicated by non-MALT lymphoma compared to controls (ΟR [95% CI]: 0.4 [0.2-0.9], p-value: 0.02).
This study identifies an increased prevalence of the BAFF-R His159Tyr mutation in patients with SS, particularly in those with SS complicated by MALT lymphoma whose disease onset occurred at a younger age.
