Understanding NF1

The cells that make up our bodies grow and multiply in a carefully controlled way. Nerve tumours appear in people with NF1 because some of their nerve cells start to grow unchecked. In 1990, researchers discovered that people with NF1 have an altered version of a gene that usually helps to keep cell growth under control. A genetic test may be able to detect this altered gene before symptoms appear, usually during the first year of life.
