Abstract The purpose of this study was to determine the prevalence of ganciclovir (GCV) resistance-conferring human cytomegalovirus (HCMV) UL97 gene mutations and UL97 polymorphisms in Korean immunocompromised patients. A partial sequence of the HCMV UL97 gene spanning codons 430 to 644 was amplified in 77 samples from 32 patients by nested polymerase chain reaction (PCR) and sequenced directly. A cysteine-to-glycine mutation at codon 592 (C592G) conferring GCV resistance was detected in a 2-year-old girl after a 40-day GCV treatment, but overall, UL97 gene mutations associated with GCV resistance were rare in GCV-treated patients. An aspartate-to-glutamate substitution at codon 605 (D605E) was detected in 29 of 32 patients (90.6%), but 17 of 19 (89.5%) GCV-naive patients also possessed D605E. These findings indicate that the D605E polymorphism, which is frequent in Korean patients and thus may be a natural sequence variant, could be a genetic marker for HCMV in Asian countries.

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
