Genome-wide association studies (GWAS) measure hundreds of thousands of single nucleotide polymorphisms (SNPs) across the genome and relate them to common diseases and traits. Once an individual's genome has been comprehensively characterized, it can potentially be related to any trait, not just the trait that was initially investigated. Many risk factors (e.g., obesity, smoking, low socioeconomic status) are common to multiple diseases yet GWAS designed to study associations between complex diseases and genetic determinants require large sample sizes that cannot be fulfilled by single studies. This talk will discuss (broadly) the different methodologic approaches research groups have used to overcome challenges and address opportunities associated with GWAS.
