What It Is

Neurofibromatosis (NF) is a group of genetic conditions in which tumours grow on the nerves. It can affect a number of different parts of the body, such as the skin, bones, eyes and brain (NHS, 2025a; National Institute of Neurological Disorders and Stroke, 2026). Most of the tumours are non-cancerous (benign), although some may become cancerous (National Institute of Neurological Disorders and Stroke, 2026). They can grow on nerves within the body, as well as on and under the skin (NHS, 2025a).

The condition can cause skin changes, bone problems and a range of other problems. In neurofibromatosis type 1 (NF1), many of the symptoms are there from birth or start during early childhood, but some do not appear until later (NHS, 2025a). Some people have mild symptoms, while for others the condition causes serious problems (NHS, 2025a). It's a genetic condition: if a parent has NF1 or NF2, each of their children has a 1 in 2 (50%) chance of inheriting it (NHS, 2025a; NHS, 2025b). However, about half of people with NF develop it because of a new (spontaneous) change in the gene, and other family members are not affected (National Institute of Neurological Disorders and Stroke, 2026).

NF1 can show up as light brown patches on the skin (café-au-lait spots), freckles in the armpits or groin, lumps on or under the skin (neurofibromas), a tumour on the nerve to the eye (optic nerve), or a curved spine (scoliosis). Children with NF1 often have learning difficulties (NHS, 2025a).

Even though there isn’t a cure, treatment can help manage the symptoms and any complications (NHS, 2025a). People with more severe symptoms need more medical attention than those with mild symptoms. NF1 and NF2 are lifelong conditions that usually get worse over time (NHS, 2025a; NHS, 2025b), so regular check-ups are important.

Neurofibromatosis Types

Type 1 (NF1): tumours called neurofibromas grow on the nerves and skin. While NF1 is rare, it is the most common type of neurofibromatosis (NHS, 2025a; National Institute of Neurological Disorders and Stroke, 2026).

Type 2 (NF2): now also called NF2-related schwannomatosis. It is rarer than NF1. Non-cancerous tumours grow on nerves in the brain, inner ear and spinal cord, and most people get tumours on the nerve in the inner ear that is important for hearing and balance (NHS, 2025b; National Institute of Neurological Disorders and Stroke, 2026). This can cause hearing loss, ringing in the ears and balance problems (NHS, 2025b). Symptoms usually appear in the late teens or early twenties, although children can sometimes have symptoms (NHS, 2025b). NF2-related schwannomatosis affects roughly 1 in 28,000 to 1 in 40,000 babies born (Evans, Blakeley and Plotkin, 2025).

Other types of schwannomatosis: these are rarer forms, caused by changes in different genes from NF2, and are now classed separately from NF2 (Evans, Blakeley and Plotkin, 2025). They can be associated with long-term pain anywhere in the body (National Institute of Neurological Disorders and Stroke, 2026).

Get Medical Help

Call 911 or go to the emergency room at your nearest hospital if you or your child have a seizure (fit) for the first time, or weakness or numbness in the face or down one side of the body (NHS, 2025b).

Get an urgent appointment with your doctor if you or your child keep getting headaches that do not go away or are getting worse, keep feeling or being sick, or have blurred vision or vision loss (NHS, 2025a).
