Normal language skills and normal intelligence in a child with de Lange syndrome.

The subject of this case report is a 2-year, 7-month-old girl with de Lange syndrome, normal intelligence, and age-appropriate language skills. She demonstrated initial delays in gross motor skills and in receptive and expressive language but responded well to intensive speech and language intervention, as well as to physical therapy. This favorable outcome provides an important example of the beneficial effects of therapy, even for clients with conditions generally believed to have a poor prognosis.
