La Dislexia del Desarrollo: Gen, Cerebro y Cognición

developmental dyslexia is a disorder characterized by difficulties in reading acquisition. recently, dyslexia has been related to four different genes which are prone-risk candidates: dyx1c1, kiaa0319, dcdc2, and robo1. these four genes participate in brain development, and anomalies in that development comprise the known elements of the biological constellation underlying dyslexia. the induction of similar brain development anomalies in experimental animals produces problems in the processing of certain sounds. in humans, similar sound processing problems are related to a reading acquisition disorder. consequently, for the first time it is possible to delineate a tentative path between a genetic characteristic, brain development variations, and behavioral and cognitive disorders related to dyslexia.
