Table 2.

Estimated contributions to heritability of SNP variants in Asthma and two related drug-response phenotypes. Heritability estimated using polygenic linear mixed modeling. Standard error is the error associated with the heritability estimate. Percent explained is the percentage of the published heritability estimates represented by the heritability.
