Prediction of susceptibility to rheumatoid arthritis by human leukocyte antigen genotyping
Rheumatic Diseases Clinics of North America

Abstract:
Recent methodologic advances now allow the precise identification of HLA genes in individuals. Population studies using these methods have pinpointed the HLA alleles strongly associated with rheumatoid arthritis (RA). This article summarizes the current status of these RA-associated HLA genes in disease susceptibility and uses that information to derive estimates of risk ratios for prediction of disease in an individual.

01:11Genome-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.

01:11Pharmacogenetics 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...
