Neurofibromatosis Type 1 (NF1) Registry Frequently Asked Questions
How do you know if you have NF1?
NF1 is diagnosed by a doctor based on a number of signs, including the presence of six or more birthmarks called café au lait macules, freckling in the armpits and groin, pigmented growths on the iris (the colored portion of the eye; Lisch nodules), neurofibromas (benign tumors on or underneath the skin or inside the body), brain tumors that arise in the visual pathway (optic gliomas), bone abnormalities, and a family member (mother or father) with NF1. For more information on NF1, please visit The Washington University NF center website:
How can I learn more about NF1?
The Washington University Neurofibromatosis (NF) Center hosts a website with educational materials, resources, and information about NF1. Please visit this site at
I have heard that both the Children’s Tumor Foundation and Washington University have NF registries. What are the major differences between the two registries?
The Washington University NF1 Patient Registry Initiative (NPRI) ( is a unique internet-based research database that collects medical information from individuals with NF1 to help physicians and researchers better understand risks for cancer and other health outcomes in children and adults with NF1. The information gained from these studies may one day help clinicians to develop personalized treatment strategies that improve the quality of life for individuals living with NF1.

The Children’s Tumor Foundation (CTF) NF Registry ( is a patient-driven tool designed to speed recruitment of NF patients, including those with NF1, NF2, and schwannomatosis, for clinical trials. This Registry will review as many actively recruiting NF clinical trials or clinical research studies as possible. Using information entered into the database, the NF Registry will seek to match patients with the trials most suitable for them, and to facilitate the connection with the trial team.
The questionnaire asks for the name of an NF1 specialist. What if I don’t have an NF1 specialist?
If you do not have an NF1 specialist, you may leave this section of the questionnaire blank.
Are there any resources to help with finding an NF1 specialist?
The Children’s Tumor Foundation has compiled a list of NF specialists in the United States and internationally that can be accessed at the link:
