1. What is new about Dyslexia
③Research, the new facts

3）Genetic factors

• The "dyslexia susceptibility" gene DYX1C1 is involved in neural migration and that the deletion
  found in a dyslexic family disrupt its function
• Genetically driven cortical abnormalities due to anomalies of cell migration : ectopias and focal microgyri
  taking place in specific areas of the left perisylvian cortex involved in phonological representation and processing,
  are the primary cause of dyslexia.
