DNAAF4 and dyslexia: The remaining genes included DNAAF4, which is associated with dyslexia and neuronal migration in the developing neocortex (46); CXCL12, controlling neurite outgrowth and axonal guidance and enhancing NPC cell survival (47); and RELN, a well-known T3-regulated gene that acts as a critical choreographer of neuronal positioning (48).
