Abstract Certain variants of human papillomavirus (HPV)type 58 are associated with an increased risk of high grade squamous intraepithelial lesions and cervical cancer. However, little is known about the persistence of HPV58 E6/E7 variants in women with incident HPV58 infections. The aim of the present study was to evaluate the presence and persistence of HPV58 E6/E7 variants in 71 women with incident HPV58 infection throughout their follow-up. These women belonged to a cohort examined in a longitudinal study of 1,610 Colombian women, who were HPV-negative and had normal baseline cytology. E6/E7 DNA regions of HPV58-positive samples were amplified and sequenced using automated direct sequencing. A total of 639 samples were analyzed from the 71 women, and 117 samples (18.3%) were HPV58-positive. HPV58 E6/E7 variants were detected in 85.5% of the samples. The T307/A694/G744/A761 variant was identified in 88% of the samples, the T307/G744 variant was identified in 9% of samples and the T187/T307/A367/G744/G793/T798/A801/T840/C852 was identified in 3% of the samples. Overall, 50% of the HPV58 infections were present after 1 year of follow-up and all infections were cleared after 7 years. Women who had first sexual intercourse at >15 years of age had a lower clearance rate than those who had sexual intercourse for the first time at

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
