Abstract The association between polymorphism of human papillomavirus type 52 (HPV52) and high-grade cervical intraepithelial neoplasia (CIN2,3) was investigated in Canadian women. HPV-52-positive endocervical specimens collected from 216 women selected from a total of 3,614 participants recruited in two case-control and two cohort studies conducted in Canada, were further analyzed by PCR-sequencing of the LCR and E6 gene. Overall, the HPV52 LCR prototype was detected more frequently in Caucasian women (69 of 132, 52.3%, 95% confidence interval (CI): 43.8%-60.6%) than in non-Caucasian women (15 of 48, 31.3%, 95% CI 19.9%-45.4%). In two cohort studies, HPV52 prototype was detected in seven of 15 (46.7%, 95% CI 24.8-69.9) HPV52 persistent infections and 14 of 35 (40.0%, 95% CI 25.5-56.5) transient infections (p = 0.76). In two case-control studies, 30 participants did not have CIN, 18 had low-grade CIN (CIN1), 64 had CIN2,3, seven had cervical cancer and the diagnosis was undefined for 27 women. Variant MTL-52-LCR-02 was detected more frequently in women with cancer (28.6%, 95% CI 7.6%-64.8%) than in women without cancer or CIN2,3 (0%, 95% CI 0.0%-9.2%; p = 0.015). CIN2,3 risk was significantly associated with a deletion at nucleotide position 7695 in the LCR (OR 4.9, 95% CI 1.2-20.8), the T7744C variation in the LCR (OR 5.7, 95% CI 1.1-32.0), and the K93R variation in E6 (OR 6.9, 95% CI 1.3-36.8), after adjusting for age, detection of HPV16 or 18 and study site. These findings indicate that HPV52 polymorphism influences risk of CIN-2,3 and possibly invasive cancer.

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.
