BACKGROUND: Non-Hodgkin lymphoma (NHL) is a major cancer in Egypt and worldwide and has many risk factors including genes involved in the immune response.
AIM: we investigated the HLA-G 14bp gene polymorphism as a risk factor for NHL and its clinic pathologic features. The study involved 150 patients with NHL and 100 healthy control. Full histories, clinical examination, C.T scan and laboratory investigations such as CBC, LDH, ?2microglobulin and HCV RNA by qualitative real time PCR were performed for all subjects. HLA-G 14bp ins/del gene polymorphism was determined by PCR.
RESULTS: in our study, del/del, ins/del and dominant genotypes increased the risk of NHL by 11.01, 10.55 and 10.88 fold respectively (p<0.001) but the recessive genotype did not increase the risk of NHL (p=0.112). Cases with the del allele had a greater risk of NHL than those with the ins allele (p<0.001). del/del and ins/del genotypes were significantly associated with higher LDH and ?2microglobulin levels (p<0.001), lower Hb and platelet values (p<0.001), extra nodal sites (p=0.001), poor performance status (p=0.04) and relapse (p=0.001). Conclusions: the results suggest that HLA-G 14bp ins/del gene polymorphism is a risk factor for NHL in our Egyptian population and is associated with poor clinical pathological features.
