A possible cause of dyslexia is now coming into focus.
Researchers at Yale say they've identified a gene that may be responsible for the reading disability. When the gene is altered, brain circuits that make it possible to read are disrupted. Scientists say they hope their findings could someday lead to improved methods to identify the disability. It's already estimated that about 10% of Americans suffer from dyslexia.
This study was published in the Proceedings of the National Academy of Sciences and presented at the American Society of Human Genetics meeting in Salt Lake City on October 28, 2005. The gene is on human chromosome 6 called dcdc2.
