Following publication of the original article [1], the authors identified an error in the heritability estimation. In particular, formula (4) should read as

$$\frac{\sum_{i=1}^{9}\,p(G_i)\cdot\big[p(Y=1|G_i)-p(Y=1)\big]^2}{p(Y=1)\,\cdot\,(1-p(Y=1))}$$

This has however no impact on the trustworthiness of the results; heritability estimates were merely provided as descriptive information.

Discussion elements remain unchanged.
