A study by Rollinson et al [63] of haplotypic variation in NHL found no increased risk associated with haplotypes of NBS1 and RAD50; however, they observed the variant rs601341 in MRE11 to have a protective effect on FL and a protective effect of an MRE11 haplotype on DLBCL. The gene discussed is RAD50; the disease is diffuse large B-cell lymphoma.
