WebbGenome wide association studies (GWAS) are hypothesis-free methods for identifying associations between genetic regions (loci) and traits (including diseases). It has long been known that genetic variation between individuals can cause differences in phenotypes. Webb22 feb. 2016 · Genome-wide association studies (GWAS) have successfully uncovered many associated loci. Such approaches typically analyze thousands of nominally unrelated individuals and search for correlations between genetic variants and a single trait of interest.
