Information for Health Care Professionals

Health Care Professionals
Through our research, in partnership with the Patient Led Research Hub – University of Cambridge, we have found that many healthcare professionals struggle to access clear guidelines on Neurofibromatosis Type 1 (NF1), as there are currently no dedicated NICE guidelines. To address this gap, we aim to simplify the process of caring for individuals with NF1 by providing access to comprehensive resources, including the ERN Genturis guidelines. While these are European guidelines and some recommendations may differ in the UK, they represent the most thorough and reliable guidance currently available.

Diagnostic criteria for Neurofibromatosis Type 1 (NF1)

A diagnosis of NF1 can be given if an individual has two or more of the following manifestations:

**Additional Genetic Criteria Updates:
  • The term “mutation” is no longer accepted; pathogenic variant is now the preferred term.
  • Genetic analysis is not REQUIRED for diagnosis but may allow for an earlier diagnosis.
  • Genetic analysis ALONE is not sufficient to diagnose NF1 – diagnosis requires a second diagnostic feature of NF1.

Body Map for Early Identification of Neurofibromatosis

At Childhood Tumour Trust, we’re proud to be championing the inclusion of a Body Map in the national Personal Child Health Record (commonly known as the Red Book). While it has not yet been adopted nationally, each NHS Trust can order their own version to be inserted at the time of printing – and CTT will cover the cost of the first set to help make this important addition accessible.

Why is a Body Map Important?

A Body Map provides a simple, clear way to record birthmarks and skin features—especially café-au-lait spots, which are one of the early signs of Neurofibromatosis Type 1 (NF1). It can also be useful for documenting Mongolian blue spots and in safeguarding contexts. By noting and monitoring these marks, healthcare professionals and parents can support earlier identification and timely referrals.

If your baby or child has any visible birthmarks or café-au-lait spots, we encourage you to download and print the Body Map below and add it to their Red Book. It could make all the difference in ensuring early support and diagnosis.
