Rare variants and handedness: spotlight on TUBB4B.

Abstract excerpt

Twin studies suggest that additive genetic effects account for about a quarter of the variance in handedness. Recently, Schijven et al. used exome-wide sequencing to provide evidence for a role of rare protein-coding variants in handedness. These included the gene encoding beta-tubulin, TUBB4B, suggesting that microtubules are relevant for handedness ontogenesis.
