What is GWA?

GWA definition and meaning on Health terms:
A genome-wide association study (GWA study) is a method that involves rapidly searching markers across the complete set of DNA or genome of many people to find genetic variations associated with a particular disease. Once the genetic associations are identified, researchers can use the information to develop better strategies to treat and prevent complex diseases such as asthma, cancer, or diabetes. As a result of the Human Genome Project, researchers now have a set of research tools such as computerised databases containing the human genome sequence, a map of human genetic variation, and a set of new technologies that can quickly and accurately analyse whole-genome samples for genetic variations that contribute to the onset of a disease.
