This set of guidelines is designed to assist the pediatrician in caring for children with Marfan syndrome confirmed by clinical criteria. Although pediatricians usually first see children with Marfan syndrome during infancy, occasionally they will be called on to advise the pregnant woman who has been informed of the prenatal diagnosis of Marfan syndrome. Therefore, these guidelines offer advice for this situation as well. Marfan syndrome is a heritable disorder of connective tissue characterized by autosomal dominant inheritance and variabffity in clinical expression. The frequency of this disorder is at least I in 10 000 in the United States.’ Approximately one fourth of cases arise by new mutation; the rest are inherited from a parent. The gene (FBN1 ) has been mapped to chromosome 15q21.1;2 the defective protein is fibrillin, an important protein in the structure of connective tissue. Specific mutations that result in defective or decreased fibrillin are being identified in persons with Marfan syndrome.4 There is considerable heterogeneity in the known mutations. The major clinical manifestations involve the skeletal, ocular, and cardiovascular systems and the skin.1 Cardiovascular abnormalities are the most lifethreatening features of Marfan syndrome, may be present at birth, manifest during ChildhOod in about 25% of affected children,6 and are progressive in about one third of those. The following manifestations occur in Marfan syndrome. They are divided into major and minor criteria.7 Skeletal on Genetics trusio acetabulae diographs).

They 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, pediatriclans are encouraged to view these guidelines in light of evolving scientific information. Clinical geneticists may be a valuable resource for the pediatrician seeking additional information or consultation. PEDIATRK3 (ISSN 0031 4005).
