Abstract

Aim: The research was conducted to study 1188 A\C polymorphism of Interleukin (IL)-12B gene for C/C, A/C and A/A genotypes in families of Hepatitis C virus (HCV) infected patients in Egypt.

Methods: Three hundreds HCV patients, 860 family members and 100 healthy subjects were studied. All family members were screened for HCV antibodies by enzyme-linked immunosorbent assay (ELISA). Positive cases were examined using Real-Time polymerase chain reaction (PCR) to confirm the presence of HCV ribonucleic acid (RNA) and detect the viral load. Molecular study of IL-12B gene was carried out on all patients, family members and controls using PCR and restriction enzyme analysis.

Results: HCV infection was confirmed in 10.6% of family members. The distribution of IL-12B gene polymorphism in patients was 2.3%, 45.7% and 52% for C/C, A/C and A/A genotypes respectively, in infected family members was 3.3%, 41.7%, 55%, in noninfected family members was 4.5%, 43.5% and 52% for C/C, A/C and A/A genotypes respectively and in control was 5%, 36% and 59% for C/C, A/C and A/A genotypes respectively. The frequency of the C/C, A/C and A/A genotype was not significantly different between the studied groups.

Conclusion: IL-12B gene polymorphism has no role in intrafamilial susceptibility of HCV transmission. The distribution of the functional 1188 A\C polymorphism of Interleukin (IL)-12B gene for C/C, A/C and A/A genotypes was not significantly different among the studied groups.

Keywords: Gene, HCV, IL12B, intrafamilial transmission, polymorphism, genepolymorphism.
