Providing a reference for people with a syndrome or inherited disorder, and those who care for them, this book describes the disorders and problems of both children and adults, and considers the day-to-day management of conditions. It is written in non-technical language for a lay readership, but aims to be detailed enough for the medical, nursing and midwifery professions. This edition has been expanded to include 20 more syndromes, as well as additional material to assist readers to contact self-help groups.
