Of the 13 single nucleotide polymorphisms (SNPs) showing significant associations with reading-related phenotypes, eight were located within DCDC2. Another study [10] tested 147 SNPs in a sample of 153 dyslexic families from Colorado and reported a nominal significance for 37 SNPs, 11 of which were located in DCDC2. In the same study, two of the five SNPs that yielded a p value ≤0.01 were located in DCDC2. Several follow-up studies using the case-control design [14, 15] have also reported positive associations for SNPs within DCDC2 with dyslexia. Here, DCDC2 is linked to dyslexia.
