There are similar anatomical and behavioral findings for other dyslexia candidate risk genes, for example, DCDC2 (rat homolog Dcdc2; Meng et al., 2005; Burbridge et al., 2008; Gabel et al., 2011; Wang et al., 2011; Adler et al., 2013) and KIAA0319 (rat homolog Kiaa0319; Paracchini et al., 2006; Threlkeld et al., 2007; Peschansky et al., 2010; Szalkowski et al., 2012; Adler et al., 2013; Centanni et al., 2014a,b), however, DYX1C1/Dyx1c1 is of particular interest for potential sex differences in dyslexia because of its relationship with estrogen. This evidence concerns the gene DNAAF4 and dyslexia.
