Committee on Genetics. The recommendations in this policy statement do not indicate an exclusive course of treatment for children with genetic disorders but are meant to supplement anticipatory guidelines available for treating the normal child provided in the American Academy of Pediatrics publication, Guidelines for Health Supervision. They are intended to assist the pediatrician in helping children with genetic conditions to participate fully in life. Diagnosis and treatment of genetic disorders are changing rapidly. Therefore, pediatricians are encouraged to view these guidelines in light of evolving scientific information. Clinical geneticists may be valuable resources for the pediatrician seeking additional information or consultation.
