Schematic of the genes within the DYX2 locus on chromosome 6p22. Genes in blue, DCDC2 and KIAA0319, have replicated associations with written and verbal language phenotypes, namely RD and LI. Regions in red mark two functional variants, READ1 in DCDC2 and a risk haplotype containing markers in KIAA0319 and TDP2, which have been functionally associated with RD and LI using animal models and molecular techniques
