Abstract Long-term exposure to antiviral therapy in immunocompromised patients favors emergence of human cytomegalovirus (HCMV) resistance mutations. Two new UL54 DNA polymerase mutations (deletion of codon 524 and N408S substitution) identified in a kidney recipient and a bone marrow recipient respectively were characterized. Marker transfer experiment through recombination into a HCMV AD169 BAC demonstrated del524 and mutation N408S confer GCV and CDV resistance. These results suggest continued mutation of UL54 under selective antiviral pressure. Characterization of each new mutation is thus required to inform genotypic assays and to better understand the functional regions of UL54 for the development of novel antivirals.

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
