=====NF 2 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.


----
Biallelic inactivation of the NF2 gene has been established as the principal underlying genetic event in
patients with sporadic and syndrome-associated vestibular schwannoma (VS). Two independent teams contemporaneously identified the NF2 gene located on chromosome 22 at 22q12.2 in [[1993]], which codes for
the tumor suppressor protein Merlin, also called schwannomin

The NF2 gene provides instructions for the production of a protein called [[merlin]], also known as [[schwannomin]]

encoding a putative membrane-organizing protein causes neurofibromatosis
type 2. Nature 1993;363:515–21.))

To date, few studies have used whole-exome sequencing, mate-pair analysis, and RNA-seq to profile genome-wide alterations in sporadic VS. Using high-throughput deep sequencing, "two-hit" alterations in the NF2 gene were identified in every tumor and were not present in peripheral blood supporting that all events were somatic. Type of NF2 gene alteration and accessory mutations outside the NF2 locus may predict phenotypic expression and clinical course
