GBE1 and dyslexia: To study the possibility that the suppression of expression involved other genes than ROBO1 in the dyslexia susceptibility haplotype, we genotyped known SNPs in the nearby genes GBE1 (341C/G, 646A/G, 1597A/G, 1794C/T, 2349T/G, 2363A/G, 2761A/T) and HTR1F (528C/T, 783T/A) in the four dyslexic individuals of the large family (Figure 1C).
