LEP and non-Hodgkin lymphoma: LEP 19G>A and LEP −2548G>A among controls, with estimated haplotype frequencies of −2548G/19A, 41.5%; −2548G/19G, 18.5%; −2548A/19G, 39.2%; and −2548A/19A, 0.8%, were in linkage disequilibrium (D=0.95), but despite the individual SNP effects, no associations between haplotypes and either NHL as a whole or FL in particular emerged.
