Neurofibromatosis type 1 (NF1) is a multisystem inherited disorder affecting the skin and peripheral nervous system, often recognized in early childhood as pigmentary findings emerge. Although clinical expression varies widely and most children show development within normal ranges, some features may appear at birth and many manifestations evolve with age. The report reviews diagnostic criteria, inheritance, major clinical and developmental manifestations, and provides monitoring and intervention guidelines to support health and quality of life while reducing risk of serious complications.

Korf, MD, PhD, FAAP,f COUNCIL ON GENETICS, AMERICAN COLLEGE OF MEDICAL GENETICS AND GENOMICS Neuroﬁbromatosis type 1 (NF1) is a multisystem disorder that primarily involves the skin and peripheral nervous system. Its population prevalence is approximately 1 in 3000 . The condition is usually recognized in early childhood, when pigmentary manifestations emerge. Although NF1 is associated with marked clinical variability, most children affected follow patterns of growth and development within the normal range. Some features of NF1 can be present at birth, but most manifestations emerge with age, necessitating periodic monitoring to address ongoing health and developmental needs and minimize the risk of serious medical complications. In this report, we provide a review of the clinical criteria needed to establish a diagnosis, the inheritance pattern of NF1, its major clinical and developmental manifestations, and guidelines for monitoring and providing intervention to maximize the health and quality of life of a child affected. INTRODUCTION Neuroﬁbromatosis type 1 (NF1) is 1 of the most common inherited genetic conditions, affecting approximately 1 in 3000 individuals.1 NF1 is a multisystem disorder in which some features may be present at birth but most are age-related manifestations. Since the publication of the article“Health Supervision for Children With Neuroﬁbromatosis,” the health supervision and treatment rationale has evolved, necessitating this update.2 In this report, we only address issues concerning the diagnosis and management of NF1, which should not be confused with neuroﬁbromatosis type 2, a separate and distinct disorder that typically presents in childhood and adolescence with cutaneous and vestibular schwannomas and has an incidence of 1 in 33000 and a prevalence of less than 1 in 50000 .1 Most pediatricians and pediatric medical subspecialists follow multiple children with NF1 in their practices, and NF1 has a wide spectrum of health implications.
