The authors searched for linkage disequilibrium (LD) in 137 triads with dyslexia, using markers that span the most-replicated dyslexia susceptibility region on 6p21-p22, and found association between the disease and markers within the VMP/DCDC2/KAAG1 locus. This work is presented in the Jan 2006 issue of The American Journal of Human Genetics (Vol. 78, pp. 52-62). Their expression data showed that DCDC2, which contains a doublecortin homology domain that is possibly involved in cortical neuron migration, is expressed in the fetal and adult CNS, which -- together with the hypothesized protein function -- is in accordance with findings in dyslexic patients with abnormal neuronal migration and maturation.
