Abstract Human cytomegalovirus UL54 DNA polymerase gene mutations that confer foscarnet resistance in clinical practice typically cluster in the amino terminal 2, palm and finger domains. Exposure to foscarnet in cell culture selected for mutations elsewhere in UL54, including amino acid substitutions S290R in the amino terminal 1 domain and E951D in the palm 2 domain. These are newly confirmed to confer foscarnet resistance and slightly decreased ganciclovir susceptibility. Other emergent substitutions N495K, T552N and T838A are known to confer foscarnet resistance, while additional ones Q783R and V798A only slightly affected susceptibility. An expanded set of domains is involved in foscarnet resistance and its genotypic diagnosis.

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.
