IRF4 and T-cell non-Hodgkin lymphoma: Two recent Chinese studies have identified SNPs associated with an increased risk of B-cell NHL (rs6773854 located between BCL6 and LPP genes on chromosome 3q27, IRF4 rs872071, and rs2647012 in HLA-region)[28, 29] and T-cell NHL (ACOXL rs17483466 and IRF4 rs872071),[28] but none of these SNPs are in immunoregulatory genes.
