Four genes have recently been proposed as candidates for dyslexia: dyslexia susceptibility
1 candidate 1 (DYX1C1), roundabout Drosophila homolog 1 (ROBO1), doublecortin domain-
containing protein 2 (DCDC2) and KIAA0319. Each gene is implicated in global brain-
development processes such as neural migration and axonal guidance, with the exception
of DYX1C1, the function of which is still unknown. The most immediate clinical prospect of
the discovery of these genes is the possibility of early identification of dyslexia via genetic …
