Abstract Mutations in the UL97 gene are the most common mechanism of human cytomegalovirus resistance to ganciclovir in transplant recipients. In this study, UL97 fragments were amplified and sequenced in 70 Chinese kidney transplant recipients who were diagnosed as having an active cytomegalovirus infection. A new mutation, C518Y, was identified in two kidney recipients, and this strain showed high-grade ganciclovir resistance by plaque reduction assay. The known mutations L595 W and C607F were detected in one recipient, but the D605E mutation was found in 42.9 % (30/70) of kidney recipients. The prevalence of this mutation was higher than that in Europe and may be associated with different regions or races.

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
