N-acetyltransferase polymorphism in Thailand
Human Heredity
|January 1, 1984
Summary
This study investigated acetylator phenotypes in Thai and Chinese populations. Results indicate a lower frequency of rapid acetylators in Thais compared to prior research.
Area of Science:
- Pharmacogenetics
- Human genetics
- Biochemistry
Background:
- Acetylator phenotype is a genetically determined trait influencing drug metabolism.
- Variations in acetylator phenotypes exist across different ethnic groups.
- Previous studies suggested specific frequencies for rapid acetylators in Thai populations.
Purpose of the Study:
- To determine the frequency of acetylator phenotypes in northeastern Thai individuals.
- To compare acetylator phenotypes between Thai and Chinese populations.
- To assess potential discrepancies with previous findings on Thai acetylator frequencies.
Main Methods:
- Phenotyping 222 individuals from northeastern Thailand.
- Analyzing acetylator status (rapid vs. slow).
- Statistical comparison between Thai and Chinese groups.
Main Results:
- 55.5% of pure Thai descent individuals were identified as rapid acetylators.
- 66.0% of Chinese individuals were identified as rapid acetylators.
- No significant differences were observed between Thai and Chinese acetylator phenotypes.
Conclusions:
- The observed frequency of rapid acetylators in Thais is lower than previously reported.
- Thai and Chinese populations exhibit similar acetylator phenotype distributions.
- Further research may be needed to clarify regional and ethnic variations in acetylator phenotypes.

Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...

Phase II biotransformation reactions are essential for detoxifying and eliminating xenobiotics, including many pharmaceutical compounds. These reactions typically involve conjugation, the covalent attachment of polar endogenous groups such as glucuronic acid, sulfate, methyl, or acetyl moieties to functional groups introduced during Phase I metabolism. The resulting conjugates are more water-soluble, enabling efficient renal or biliary excretion.The major classes of Phase II enzymes include...

01:27Pharmacogenetics of Drug Metabolism: Overview
102
Genetic polymorphism in drug metabolism is crucial to the inter-individual variability observed in drug responses. Drug metabolism primarily involves the chemical modification of drugs and other xenobiotics to enhance their elimination by increasing their polarity. Two main classes of enzymes mediate this biotransformation process: Phase I enzymes, primarily cytochrome P450s, catalyze oxidation and reduction reactions, while other enzymes, such as esterases, mediate hydrolysis, and Phase II...

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

01:24Phase II Reactions: Acetylation Reactions
991
Acetylation, a phase II biotransformation reaction, introduces an acetyl group to drugs or their metabolites. Acetyltransferase enzymes facilitate this reaction, which resembles α-amino acid conjugation due to the addition of a functional group to the drug molecule.
The substrates for acetylation are typically drugs or their metabolites with an amino, sulfonamide, or hydrazine functional group. Acetylation can occur at several points in the drug molecule, including primary, secondary, and...

19.7K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...
