Basic Characteristics of Mutations
Mutation Site Q129L
Mutation Site Sentence The testing of reagents kits to detect HBsAg using twi panels containing recombinant and native variants of HBsAg, demonstrated that these kits enable to detect various sero-vatriants of HBsAg (ayw2, adw2, ayw3varA, ayw3varB, adrq-) in concentration 0.1-0.01 IU/l and the so called elusive mutant forms of HBsAg of recombinant and native origin (G145R, Q129R, Q129H, Q129L, T143K, T126N, T126S, D144A, M133L, K141E and P142S).

Abstract The detection of HBsAg in blood serum using immune-enzyme analysis techniques decisively matters both for diagnostics of acute and chronic hepatitis B and screening of donor's blood and its components, controls of persons from risk groups of hepatitis B injection. The making of panels containing wide specter of samples of blood serums with sero-variants and mutant forms of surface antigen of hepatitis B virus widespread on the territory of the Russian Federation is necessary to control analytic and diagnostic sensitivity of test systems for detecting HBsAg. The testing of reagents kits to detect HBsAg using twi panels containing recombinant and native variants of HBsAg, demonstrated that these kits enable to detect various sero-vatriants of HBsAg (ayw2, adw2, ayw3varA, ayw3varB, adrq-) in concentration 0.1-0.01 IU/l and the so called elusive mutant forms of HBsAg of recombinant and native origin (G145R, Q129R, Q129H, Q129L, T143K, T126N, T126S, D144A, M133L, K141E and P142S). At that, the sensitivity can differ during the detection of native and recombinant mutant forms. The results testify the importance of using the panels both with recombinant and native samples containing the mutant forms of HBsAg in evaluation of sensitivity of reagents kits.

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.
