Gene sifting for gene snipping: GWAS as a source of gene editing targets

When genome-wide association studies (GWAS) first started appearing 10 years ago, they were heralded as the answer to connecting human genetic variation to human disease. These kinds of studies—which sift population-level genetic data—have revealed thousands of genetic variations associated with diseases, from age-related macular degeneration to obesity to diabetes.

However, thus far GWAS have largely come up short when it comes to finding new therapies. Few significant drug targets have come to light based on GWAS data (though some studies suggest that these studies could help drug makers find new uses for existing molecules).

Part of the problem may be that, until now, the right tools haven’t been available to exploit GWAS data. But a few recent studies—including two out of Dana-Farber/Boston Children’s Cancer and Blood Disorders Center—have used GWAS data to identify therapeutically promising targets, and then manipulated those targets using the growing arsenal of gene editing methods.

Does this mean that GWAS’ day has finally come?
