Analyzing DNA samples from 50 pairs of twins and 358 other members of families with serious reading problems, the scientists focused on a region of chromosome No. 6. There they found characteristic genetic patterns in the subjects who were known to suffer from dyslexia. Within the next several years, they expect to isolate the specific gene or genes involved in the disorder. Dyslexia could then be diagnosed with a simple blood test, and young children could be given remedial reading help before the stigma of failure hobbles them.
