Elisabeth Raab Accelerator of Science to End Neurofibromatosis (ERASEnf)

has identified critical gaps in care and research that limits the development of innovative care models that improve the overall quality-of-life in neurofibromatosis patient population. ERASEnf is dedicated to building a collaborative teams focusing on biological, psychological and sociological well-being of patients with neurofibromatosis. 


  1. Advance our understanding of the biology of neurofibromatosis related tumors and develop novel treatment options
  2. Advance research into innovative care models that take into consideration the psychological and sociological domains of well-being in neurofibromatosis


To take a holistic approach to the neurofibromatosis condition and be a catalyst for innovation in neurofibromatosis management.

Mission Statement



Neurofibromatosis cured together



Develop multi-disciplinary collaborations to focus on biological, psychological and  sociological research that advance quality of life in neurofibromatosis

Anonymous $11 million gift to support and expand neurofibromatosis research at UHN’s Krembil Brain Institute

Toronto (May 17, 2022) – On World Neurofibromatosis Awareness Day, UHN Foundation announces an anonymous gift of $11 million in support of neurofibromatosis (NF) research. NF is a genetic disorder affecting approximately one in 10,000 Canadians. It results in the development of innumerable tumours throughout the nervous system, including the brain, spinal cord and peripheral […]
