Saturday, September 21, 8:00am – 12:00pm Planning Committee: Scott Plotkin, MD, PhD, Massachusetts General Hospital; Elizabeth Schorry, MD, Cincinnati Children's Hospital; Pamela Trapane, MD, University of Florida Health Jacksonville; Nicole Ullrich, MD, PhD, Boston Children’s Hospital Revised Diagnostic Criteria for NF1, NF2, and Schwannomatosis Saturday, September 21, 8:05am – 8:30am Eric Legius, MD, PhD, University of Leuven, Belgium Saturday, September 21, 8:30am – 9:00am Scott Plotkin, MD, PhD, Massachusetts General Hospital When revising the diagnostic criteria we used the following guiding principles: represent best consensus among NF experts, address diagnostic (rather than clinical management) issues, be broadly representative of medical specialties and national groups, accessible to generalists as well as NF specialists, recognize advances in genetics over last 30 years without requiring genetic analysis for diagnosis, be acceptable in different countries and health care systems, now and in the coming years. We used the anonymous Delphi procedure to ask the opinion of many specialists in the field about possible changes to the criteria. We met with a large group of experts in New York in June 2018 to discuss the Delphi results and proposed possible changes in the criteria and the science behind it. We subsequently performed a second round of Delphi in October 2018 and presented preliminary revised diagnostic criteria at the Global Neurofibromatosis Meeting in Paris in November 2018. Experts were asked to provide feedback after the Paris meeting. We asked non-expert specialists from different specialties to provide feedback on the use and clarity of the criteria. Finally the representatives from patient organizations were asked to provide feedback. We will present the latest version of the revised criteria and explain the process how we got there.

Miller, MD, PhD and Nicole Ullrich, MD, PhD, Boston Children's Hospital Clinical management guidelines for children with NF1 were revised and updated in 2019. These new American Academy of Pediatrics (AAP) and American College of Medical Genetics (ACMG) guidelines for the care of individuals with NF1 have an emphasis on decision-making for providers with regards to clinical management. Updates related to differential diagnosis and genetic testing is also addressed. Based on promising results of recent clinical trials, children with NF1 now have new treatment options available, some of which have become standard of care. This educational session will help attendees to identify changes they could make in their practice related to guidelines for ongoing management of children with neurofibromatosis type 1, as well as identifying children who may be appropriate for intervention with novel therapeutics.
