Abstract A case-control study was conducted on 1986 Hong Kong women to assess the risk of human papillomavirus (HPV) type 16 variants for cervical neoplasia. In total, 255 women were HPV-16 positive and were analyzed for E6 and E7 sequence variation. Two novel substitutions at E6 (T86I and Q116E) and 1 at E7 (R66W) were found. Most HPV-16 variants were of Asian (50.6%) or European (44.3%) lineage, and both lineages showed similar risk associations for high-grade and invasive cervical neoplasia. No increased risk was observed for the subclasses European variant and European 350G, which carry a higher risk for invasive cancer in some Western populations. The E7 N29S substitution, reported to have a higher risk in Korean women, was found equally distributed among normal and various degrees of neoplasia. The epidemiology and risk implication of HPV-16 variant infection in Hong Kong differ markedly from other parts of the world.

Mutation Information
Note
Basic Characteristics of Mutations
  • Mutation Site: The specific location in a gene or protein sequence where a change occurs.
  • Mutation Level: The level at which a mutation occurs, including the nucleotide or amino acid level.
  • Mutation Type: The nature of the mutation, such as missense mutation, nonsense mutation, synonymous mutation, etc.
  • Gene/Protein/Region: Refers to the specific region of the virus where the mutation occurs. Including viral genes, viral proteins, or a specific viral genome region. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main
  • Gene/Protein/Region studied in the article is marked.
  • Genotype/Subtype: Refers to the viral genotype or subtype where the mutation occurs. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main Genotype/Subtype studied in the article is marked.
  • Viral Reference: Refers to the standard virus strain used to compare and analyze viral sequences.
Functional Impact and Mechanisms
  • Disease: An abnormal physiological state with specific symptoms and signs caused by viral infection.
  • Immune: The article focuses on the study of mutations and immune.
  • Target Gene: Host genes that viral mutations may affect.
Clinical and Epidemiological Correlations
  • Clinical Information: The study is a clinical or epidemiological study and provides basic information about the population.
  • Treatment: The study mentioned a certain treatment method, such as drug resistance caused by mutations. If the study does not specifically indicate the relationship between mutations and their correspondence treatment, the main treatment studied in the article is marked.
  • Location: The source of the research data.
Literature Information
