Abstract The reasons that lead some individuals living with the Human T Lymphotropic Virus 1 (HTLV-1) to develop HAM/TSP are still unclear. To better understand the viral genetic factors that may be associated with the development of HAM/TSP, this study aims to evaluate the impact of HTLV-1 genome mutations on the development of this disease through a systematic review. This review followed the PRISMA guidelines and was registered in the PROSPERO database. The search for articles was performed in PMC, PubMed, Lilacs, SciELO, and Embase databases using the following search descriptors: HTLV-1, HAM/TSP, mutation, polymorphism, genetic variation, and sequenc*. From the 1,929 articles found in the search, 20 were selected according to the pre-defined inclusion and exclusion criteria. A total of 619 HAM/TSP cases were compared with 555 AC controls. The mutations possibly related to the disease progression were detected in hbz (R119Q), tax (A7959V), ORF-I (R88K, P86S, S69G, P45L, L40F, C39R, CR9Y), and gp46 (V247I, N93D, S72G) genetic regions. The data collected and analyzed here indicate that mutations in the HTLV-1 genome could play an important role in the chronic inflammatory state and may be related to the development of HAM/TSP.

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.
