Until recent years, much of the research on the molecular basis of dyslexia focused on a handful of candidate genes (e.g., ROBO1, KIAA0319, DCDC2, and DYX1C1) that were identified through linkage analysis in families, and then followed up via fine-mapping of association with common variants within those genes (see (Carrion-Castillo et al. 2013) for a review). Here, ROBO1 is linked to dyslexia.
