Genome-wide association study

A Genome-Wide Association Study (GWAS) is a research method used to identify genetic variations linked to specific traits or diseases. Researchers scan the entire genome of many individuals to find small differences in DNA, called single nucleotide polymorphisms (SNPs), that may be associated with a particular condition. By comparing the genomes of people with and without the condition, scientists can pinpoint genetic markers that may help explain risk factors for diseases or provide insights into biological processes. This approach enhances our understanding of genetics and can inform personalized medicine and treatment strategies.
