What is the official name of the NF2 gene?
The official name of this gene is “neurofibromin 2 (merlin).”
NF2 is the gene's official symbol. The NF2 gene is also known by other names, listed below.

What is the normal function of the NF2 gene?
The NF2 gene provides instructions for the production of a protein called merlin, also known as schwannomin. This protein is made in the nervous system, particularly in specialized cells that wrap around and insulate nerves (Schwann cells).
Merlin is believed to play a role in controlling cell shape, cell movement, and communication between cells. To carry out these tasks, merlin associates with the internal framework that supports the cell (the cytoskeleton). Merlin also functions as a tumor suppressor protein, which prevents cells from growing and dividing too fast or in an uncontrolled way.
How are changes in the NF2 gene related to health conditions?
Where is the NF2 gene located?
