As part of our investigations into the putative role of the KIAA0319 and KIAA0319L genes in dyslexia susceptibility, we have recently reported the generation, neuro-anatomical analysis and behavioural characterisation of knock-out (KO) mice for the homologous genes D130043K22Rik29 and AU04032030, respectively. The gene discussed is KIAA0319L; the disease is dyslexia.
