Genome-Wide Association Study

Meaning

A Genome-Wide Association Study (GWAS) is a powerful research method that involves rapidly scanning the entire genome of a large number of individuals to find genetic variations associated with a particular disease or trait. This systematic analysis identifies single nucleotide polymorphisms (SNPs) that occur more frequently in people with a specific condition, such as type 2 diabetes or premature menopause. In endocrinology, GWAS is a key tool for uncovering the complex genetic underpinnings of polygenic disorders and for advancing precision medicine.
