Genetic defect linked to visual impairment in dyslexics – report by MNT
A excerpt from the news report:
- The researchers used a series of visual tests to compare typical readers with two groups of dyslexics — one with and one without a specific deletion in the DCDC2 gene.
- The subjects were presented with images of patterned black and white lines and asked to determine whether the image was moving horizontally or vertically.
- Dyslexics with the genetic deletion failed to detect the motion of the image, although they were able to determine the orientation of the lines.
- The group of dyslexics with a normal copy of the DCDC2 performed similarly to the normal readers, with only a minor impairment in motion detection.
