genome-wide association studies (GWAS)
Genome-wide association studies (GWAS) are research methods used to identify genetic variations linked to specific traits or diseases. By analyzing the genomes of large groups of individuals, researchers can find common genetic markers associated with conditions like diabetes or heart disease. This helps in understanding the genetic basis of these diseases.
In a GWAS, scientists compare the DNA of individuals with a particular trait to those without it. They look for differences in single nucleotide polymorphisms (SNPs), which are variations in the DNA sequence. The findings can lead to better prevention, diagnosis, and treatment strategies for various health issues.
