Abstract OBJECTIVE: To identify genetic variants in the E6 gene of HPV 16 and to examine the association between these variants and cervical cancer development. METHODS: Cervical samples were collected from 72 patients with cervical cancer and 72 age-matched control subjects, all from Hubei Province, China. HPV 16 sequence was detected with E6 gene-specific polymerase chain reaction, and variants were identified by DNA sequencing. RESULTS: HPV 16 was detected in 81% of the patients and 43% of control subjects, respectively. The rank orders of incidence of HPV 16 prototype and E6 variants were as follows: D25E (62%), the prototype (17%), E113D (9%), L83V (6%) in case subjects; the prototype (71%), D25E (23%), L83V/E113D (7%) in control subjects. The odds ratio of HPV 16 E6 variant was higher than that of prototype (RR=11.73, 95% CI=4.18-32.94, P=0.0001). CONCLUSION: The D25 E variant is the most prevalent E6 genomic variant in Hubei, China. The presence of HPV 16 E6 variant in cervical intraepithelial neoplasia (CIN) lesions may serve as a useful predictor of clinical outcome of the disease.

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.
