The most frequently replicated locus is DYX2 on chromosome 6p21.3, and the most frequently replicated dyslexia genes on DYX2 are KIAA0319 and DCDC2 (Deffenbacher et al., 2004; Francks et al., 2004; Meng et al., 2005; Brkanac et al., 2007; Zhao et al., 2016). This evidence concerns the gene KIAA0319 and dyslexia.
