The dyslexia linkage findings45 have been related to a specific SNP haplotype within ROBO148, a neighbouring gene of ROBO2. In animal models, Robo1 and Robo2 are mostly co-expressed and it has been shown that both receptors function cooperatively, for example, with respect to the guidance of most forebrain projections49. The gene discussed is ROBO1; the disease is dyslexia.
