Abstract Antiretroviral drug resistance has become a major threat to the adequate management of human immunodeficiency virus (HIV) infection, but little attention has been paid to the spread and evolution of drug-resistant strains in the family. Here, we described a case of transmitted as well as acquired HIV drug resistance among a father, mother and infant. Epidemiological data were obtained retrospectively. Drug resistance mutations (DRMs) of three patients were tested using a validated In-house Sanger-based sequencing (SBS) method and the Vela next-generation sequencing (NGS) platform. Gene evolution analysis was also performed. According to the epidemiological history and phylogenetic data, in late pregnancy of the mother, the infant's father transmitted HIV-1 to her, and then the mother to the baby, leading to the transmission of V106I as a common mutation of three persons. The mutant frequency was 99.57% (father), 95.38% (mother) and 99.73% (infant), respectively. Mother also acquired K101E (41.03%), K103N (27.56%) and minor mutation of V106M (4.30%) after improperly discontinuing antiretroviral regimen of lamivudine (3TC), tenofovir (TDF) and efavirenz (EFV). Such acquired mutations increased the drug resistance scores on non-nucleoside reverse transcriptase inhibitors (NNRTIs) doravirine, EFV, etravirine, nevirapine and rilpivirine from 10, 0, 10, 10 and 10 to 65, 135, 25, 150 and 55, respectively. Therefore, sexually transmitted diseases, especially DRMs of HIV-1 in families, are of concern and draw attention to the need for enhanced drug-resistance prevention efforts, and accurate surveillance by more sensitive methods in complicated cases.

Mutation Information
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.
