Common SNPs explain a large proportion of the heritability for human height

Peter Visscher and colleagues report an analysis of the heritability explained by common variants identified through genome-wide association studies. They find that 45% of the variance for height can be explained by using a linear model to simultaneously consider the combined effect of common SNPs. SNPs discovered by genome-wide association studies (GWASs) account for only a small fraction of the genetic variation of complex traits in human...
