KIAA0319
KIAA0319 is a protein which in humans is encoded by the KIAA0319 gene.[1][2]
Clinical significance
Variants of the KIAA0319 gene have been associated with developmental dyslexia.[3]
Reading disability, or dyslexia, is a major social, educational, and mental health problem. In spite of average intelligence and adequate educational opportunities, 5 to 10% of school children have substantial reading deficits. Twin and family studies have shown a substantial genetic component to the disorder, with heritable variation estimated at 50 to 70%.[1]
Function
The KIAA0319 protein is expressed on the cell membrane and may be involved in neuronal migration. Furthermore KIAA0319 follows a clathrin-mediated endocytic pathway[4]
