## Abstract

Project Summary/Abstract
Dyslexia (DYS) is a common developmental disorder with a strong genetic component which can have
a significant impact on academic and vocational success as well as emotional well-being. Children with
this disorder have reading scores that are at least 1 standard deviation below their age- and grade-
matched peers. In spite of these diagnostic criterion, there is a great deal of heterogeneity within this
label, both with regard to the severity of the core deficit(s) as well as in the genetic basis of the
disorder. This heterogeneity, combined with a lack of a strong understanding of these mechanisms,
leads to a one-size-fits all approach to intervention and a significant portion of individuals do not
respond to the intervention option offered. Association studies in humans suggest that the dyslexia-
susceptibility gene DCDC2 is associated with anatomical deficits in the brain as well as deficits on tasks
that require speed. The current studies will evaluate whether this gene is causally related to these
deficits by utilizing a novel knockout rat model recently developed by the PI. If it is confirmed that this
gene does impact anatomy and rapid auditory processing, it would suggest that individuals with
dyslexia that carry a variant in this gene may respond more effectively to interventions targeting these
specific skills.
