Genetic Disorders

Fragile X syndrome is believed to be the most common genetic cause of mental retardation, even more common than Down syndrome. It can result in a wide range of developmental delays, learning disabilities, and physical characteristics -- which all tend to be more pronounced in boys than in girls. At last, there is a comprehensive book on fragile X syndrome for parents. The first and only book of its kind, this book provides a complete, sensitive introduction to fragile X syndrome, an inherited, genetic condition caused by a mutation on the X-chromosome. This new guide is written by an experienced, caring group of parents, doctors, therapists, and teachers, who offer an in-depth look at the issues and concerns affecting children and their families.
