Rheumatoid arthritis is an autoimmune disease with a strong association with DR4 in many populations. In the Thai population, rheumatoid arthritis is associated with DRB1*0405. To evaluate the role of polymorphism in TAP and HLA-DM genes, which are important in antigen processing and presentation in predisposition to rheumatoid arthritis, 82 Thai patients with rheumatoid arthritis and 100 unrelated normal controls were studied. TAP and HLA-DM typing was performed by ARMS-PCR and PCR-SSO method, respectively. There was no difference in the distribution of TAP1, TAP2, DMA, and DMB genes between the patients and controls. This study suggested that TAP and HLA-DM genes do not confer susceptibility to rheumatoid arthritis.

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

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...
