Abstract:

Genetic polymorphism within the regulatory regions of tumor necrosis factor-alpha (TNF-α) and Lymphotoxin-alpha (LT-α) may be involved in the development of lymphoid malignancies. The aim of the current study was to investigate the effect of TNFα−308 and LTα+252 genetic polymorphism on susceptibility to non-Hodgkin lymphoma (NHL) in Egypt. Genotyping of the studied genes by restriction fragment length polymorphism polymerase chain reaction was conducted on 84 NHL and 100 healthy controls and revealed that TNFα−308 homotype (AA) was significantly higher in NHL patients and conferred sixfold increased risk of NHL (OR = 5.9, 95%CI = 2.3–16.1). Moreover, TNFα/LTα high-producer haplotypes were significantly higher in NHL patients and conferred increased risk of NHL (OR = 4.59, 95%CI = 2.19–9.42).
