Dyslexia’s DNA Clue: Gene takes stage in learning disorder
By Bruce Bower
For the first time, scientists have identified a gene that appears to influence the development of at least some cases of dyslexia.
This learning disorder is characterized by difficulties in perceiving sounds within words, spelling and reading problems, and troubles with written and oral expression. It’s estimated that dyslexia affects at least 1 in 25 people. Although scientists are investigating dyslexia’s suspected neural roots (SN: 5/24/03, p. 324: Scripted Brains: Learning to read evokes hemispheric trade-off), the condition’s causes remain unknown.
