WebGenome-wide association studies (GWAS) represent an emerging method to identify important genes which modulate human disease. GWAS primarily focus on relationships between SNPs and disease characteristics (traits). Briefly, this method scans the genome for SNPs, and can analyze hundreds or even thousands of SNPs simultaneously. WebA association study (GWAS) evaluates one single-nucleotide polymorphism (SNP) at a time for association to a phenotype or outcome. In the disease case/control setting, this is typically performed through a goodness-of-fit test or logistic regression, which report association odds ratios, standard errors, and P values.
