genome-wide association study
(JEE-nome ... uh-SOH-see-AY-shun STUH-dee)
A study that compares the complete DNA of people with a disease or condition to the DNA of people without the disease or condition. These studies find the genes involved in a disease, and may help prevent, diagnose, and treat the disease. Also called GWAS, WGA study, and whole genome association study.
Genome-wide association studies (GWAS) are a way for scientists to identify genes involved in human disease. This method searches the genome for small variations, called single nucleotide polymorphisms or SNPs (pronounced ???snips???), that occur more frequently in people with a particular disease than in people without the disease. Also called GWAS, WGA study, and whole genome association study.
