DCDC2 and dyslexia: Linkage studies pointed at nine chromosomal regions (termed DYX1 to 9) and subsequent association studies identified several dyslexia‐related genes within these regions, for example, DYX1C1, DCDC2, KIAA0319, and ROBO1. Moreover, associations with genes outside these regions such as CMIP, CNTNAP2, and FOXP2 have also been repeatedly reported (Peter et al., 2011; Scerri et al., 2011; Vernes et al., 2008).
