3′ untranslated region A>C (rs3212227) polymorphism of Interleukin 12B gene as a potential risk factor for Hodgkin’s lymphoma in Brazilian children and adolescents

Interleukin 12 plays an important role in immunoregulation between the T helper 1/T helper 2 lymphocytes and in the antiviral and antitumor immune response. The aim of this study was to investigate the possible association between the interleukin 12B polymorphism rs3212227 and the risk to develop Ho...

Description
Summary:Interleukin 12 plays an important role in immunoregulation between the T helper 1/T helper 2 lymphocytes and in the antiviral and antitumor immune response. The aim of this study was to investigate the possible association between the interleukin 12B polymorphism rs3212227 and the risk to develop Hodgkin’s lymphoma in childhood and adolescents. A total of 100 patients with Hodgkin’s lymphoma and a group of 181 healthy controls were selected at random from a forensic laboratory of the University of Pernambuco. The AA genotype was detected in the controls (53.04%) and the AC genotype was found in the patients (54%). The AC genotype showed an association with the development of Hodgkin’s lymphoma (odds ratio = 2.091, 95% confidence interval = 1.240–3.523, p = 0.007). When AC + CC genotypes were analyzed together, an increase in risk of 1.9 times more chances for HL development could be observed (odds ratio = 1.923, 95% confidence interval = 1.166–3.170, p = 0.014). However, there was no association between the AC and CC genotypes of the interleukin 12B polymorphism with the clinical risk group (p = 0.992, p = 0.648, respectively). Our results suggest that the presence of the C allele may be contributing to the development of Hodgkin’s lymphoma in children and adolescents.
