The functional IL1B (rs1143627) C allele and IL1B (rs16944) A allele were associated with a decreased risk of FL but not DLBCL, a trend for an association with the IL1B gene was observed in the Interlymph study [10], however substantial difference was observed between the included cohorts.[10] The IL10RB (rs1058867) SNP was earlier investigated in a pooled study [12] reporting an association with FL; results we failed to confirm, whereas we observed a significant association in DLBCL where a decreased risk was shown for DLBCL carries of the G allele. Here, IL1B is linked to diffuse large B-cell lymphoma.
