Genome-wide association studies (GWASs) uncovered thousands of genetic variants associated with hundreds of diseases. However, the variants that reach statistical significance typically explain only a small fraction of the heritability and hence, the heritability estimates obtained in GWAS are much lower than those of traditional quantitative methods. This has been called the “missing heritability problem”.
