Two other SNPs in the 5′ untranslated region (UTR) of DYX1C1 have been reported to associate with dyslexia both singly and in a haplotype with rs3743205 (Dahdouh et al., 2009) and to be recognition sites for transcription factors TFII-I and Sp1: TFII-1 toboth alleles of rs3743205 and Sp1 to rs16787 (−10310C > A) and rs12899331 (−10567T > C). This evidence concerns the gene GTF2I and dyslexia.
