The NF1 gene, or Neurofibromin 1 gene, is a gene that provides instructions for making a protein called neurofibromin. This protein is involved in regulating cell growth by acting as a tumor suppressor. It achieves this by turning off a protein called Ras, which promotes cell division. When the NF1 gene is mutated, it can lead to uncontrolled cell growth and the formation of tumors.
