Affects 1 in 3000; caused by NF1 tumour suppressor mutations causing skin lesions nerve tumours and elevated cancer risk. ~50% are de novo.
How Genetic Is Neurofibromatosis Type 1?
Neurofibromatosis Type 1 has a strong genetic basis. Research estimates heritability at approximately 100%, meaning genetic factors account for the majority of variation in whether individuals develop this condition.
Key genes associated with Neurofibromatosis Type 1: NF1. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.

If a first-degree relative (parent, sibling, or child) has been diagnosed, your own risk may be significantly elevated. Discussing your family history with a healthcare provider or genetic counsellor is strongly recommended.
