The presence of two minor alleles at rs6935076 is associated with high variability in children with dyslexia. Five children, all with dyslexia, had two minor alleles at a specific SNP in KIAA0319. These children exhibited significantly higher variability compared to children with 1 (N = 7, including 5 dyslexic) or 0 (N = 10, including 4 dyslexic) minor alleles at this location. * = one-tailed t-test, p = 0.01.
