KIAA0319 was found to be expressed less in individuals with a specific haplotype associated with dyslexia—variant rs9461045 (Paracchini et al. 2006), later on proven to be caused by the introduction of a binding site for the transcription factor OCT1 in the KIAA0319 promoter (Dennis et al. 2009). Here, KIAA0319 is linked to dyslexia.
