TABLE 3.

Proportion of variance in QT interval duration explained by covariates and estimates of heritability in the European-American sample with and without each SNP individually under an additive genetic model

Covariates Proportion of variance attributable to covariates Proportion of variance attributable to each SNP h 2 r
All European Americans
 RR interval, age, sex, diabetes, and BMI 0.631 0.476 ± 0.14
 Covariates plus rs10494366 0.643 0.012 0.468 ± 0.14
 Covariates plus rs10918594 0.651 0.020 0.418 ± 0.14
Diabetic European Americans only
 RR interval, age, sex, and BMI 0.624 0.323 ± 0.18
 Covariates plus rs10494366 0.639 0.0152 0.294 ± 0.18
 Covariates plus rs10918594 0.646 0.022 0.266 ± 0.17

h2r data are means SE. h2r represents the residual heritibility after adjusting for covariates and each SNP individually.
