Further evidence for a susceptibility locus contributing to reading disability on chromosome 15q15-q21.

Our data and the previous reported findings present convincing evidence for a dyslexia-related gene within the identified linkage and LD region on chromosome 15q. However, at this stage it seems difficult to determine whether the linkage and association findings point to more than one susceptibility loci within this region. A definite answer to this question will require systematic single nucleotide polymorphism-based LD mapping within the implicated region, which should lead to the identification of the true dyslexia susceptibility gene(s).
