GB virus-C (GBV-C)/hepatitis G virus (HGV) is a persistent, often asymptomatic RNA virus. Its role in causing disease remains unclear, and it shows significant genetic variation across global populations.

Area of Science:

  • Virology
  • Hepatitis Viruses
  • Infectious Diseases

Background:

  • GB virus-C (GBV-C), also known as hepatitis G virus (HGV), is a Flaviviridae family member.
  • GBV-C/HGV is a positive-strand RNA virus with potential variations in its core protein.
  • Transmission occurs parenterally and likely sexually.

Purpose of the Study:

  • To investigate the characteristics and prevalence of GBV-C/HGV infections.
  • To explore the potential pathogenicity of GBV-C/HGV.
  • To analyze the genetic diversity and classification of GBV-C/HGV.

Main Methods:

  • Review of existing literature on GBV-C/HGV.
  • Analysis of epidemiological data on infection rates.
  • Examination of experimental data, including chimpanzee studies.

  • Genomic sequence variation analysis.

    • Main Results:

    • Most GBV-C/HGV infections are asymptomatic and persistent.
    • No clear correlation between GBV-C/HGV infection and liver dysfunction was found.
    • Chimpanzee studies showed no evidence of liver pathogenesis.
    • Prevalence varies globally, higher in developing countries (8-14.6%) than developed (1-1.4%).
    • GBV-C/HGV exhibits significant genome variation, leading to proposed classification into at least four genotypes.

    Conclusions:

    • GBV-C/HGV is considered an 'orphan' virus due to its unclear disease association.
    • Further research is needed to determine the disease-inducing potential of GBV-C/HGV.
    • Global genetic diversity suggests distinct geographical strains of GBV-C/HGV.
