What is the official name of the NF1 gene?
The official name of this gene is “neurofibromin 1.”
NF1 is the gene's official symbol. The NF1 gene is also known by other names, listed below.

What is the normal function of the NF1 gene?
The NF1 gene provides instructions for making a protein called neurofibromin. This protein is produced in many types of cells, including nerve cells and specialized cells called oligodendrocytes and Schwann cells that surround nerves. These specialized cells form myelin sheaths, which are the fatty coverings that insulate and protect certain nerve cells.
Neurofibromin acts as a tumor suppressor protein. Tumor suppressors normally prevent cells from growing and dividing too rapidly or in an uncontrolled way. This protein appears to prevent cell overgrowth by turning off another protein (called ras) that stimulates cell growth and division. Other potential functions for neurofibromin are under investigation.
How are changes in the NF1 gene related to health conditions?
Where is the NF1 gene located?
Cytogenetic Location: 17q11.2
Molecular Location on chromosome 17: base pairs 31,007,873 to 31,377,677
