the Pediatric Group & families too will be joining the Neurodevelopmental Diagnostic Center for Young Children in developing a screening tool for early detection and treatment of a chromosomal disorder that affects many children. The XXY Sex Chromosome Disorder is one of the most common causes of learning disabilities, dyslexia and speech and language delays in children, and remains unidentified in 75% of these cases. If your child suffers from any type of learning or developmental difficulties, we invite you to participate in this important initiative. For more information, call the Study Coordinator at (410) 721-2273, extension 8843, or get the facts with the helpful BROCHURE.
