Study reveals link between dyslexia genes and brain structure

Dyslexia is a common learning difficulty in which genes often play a role. How do genes associated with dyslexia relate to brain structure in the general population? In a large-scale study published in Science Advances, a team of scientists led by the Max Planck Institute for Psycholinguistics in Nijmegen found that genetic variants that increase the chance of dyslexia were associated with differences in brain areas involved in motor coordination, vision, and language.
