Genome-wide association studies (GWAS) are used to analyze genetic differences between people with specific illnesses and healthy individuals. The purpose of GWAS is twofold:
1. Explore the connection between specific genes (genotype) and their outward expression (phenotype)
2. Help identify genetic risk factors for the development or progression of specific illnesses
Portions of the annual Human Genome Project (HGP) budgets of the DOE (3%) and NIH (5%) were devoted to studying the ethical, legal, and social implications (ELSI) of genome research. Examples of topics that fall under such ELSI programs include:
