LOCATION
22q12.2
LOCUSID
ALIAS
ACN,BANF,SCH,merlin-1
FUSION GENES
DNA/RNA
Description
exons 17 exons (1-15, 17 constitutive, 16 alternatively spliced); spans 120 kb; open reading frame: 1.8 kb
Transcription
alternate splicing, in particular after exon 15
Proteins
Description
called merlin, schwannomin, or SCH; isoform 1 595 amino acids, isoform 2 590 amino acids (due to inclusion of exon 16 in transcript) ; 66 KDa; NH2 -- FERM domain -- large a helix domain -- COOH
Expression
wide: in lung, kidney, ovary, breast, placenta, neuroblasts; high in fetal brain
Localisation
membrane associated interacts with integral membrane proteins and actin-cytoskeleton
Function
membrane-cytoskeleton anchor (as APC also appears to be); role in the development of extraembryonic structures before gastrulation; has characteristics of a tumour suppressor, as has been found in sporadic as well as neurofibromatosis type 2 induced schwannomas and meningiomas
Homology
ezrin, radixin, moesin, members of the erythrocytes band 4.1 family, especially in the N-terminal FERM domain
Mutations
Germinal
inborn condition of neurofibromatosis type 2 patients: protein truncations due to various frameshift deletions or insertions or nonsense mutations; splice-site or missense mutations are also found; phenotype-genotype correlations are observed (i.e. that severe phenotype are found in cases with protein truncations rather than those with amino acid substitution)
Somatic
mutation and allele loss events in tumours in neurofibromatosis type 2 and in sporadic schwannomas and meningiomas are in accordance with the two-hit model for neoplasia, as is found in retinoblastoma
Implicated in
Entity name
neurofibromatosis type 2
Disease
autosomal dominant tumor prone disease; neurofibromatosis type 2 (NF2: the same symbol is used for the disease neurofibromatosis type 2 and the gene) is an hamartoneoplastic syndrome
Prognosis
hamartomas have a potential towards neoplasia; those, in NF2, are
The tumors of NF2 are slow-growing benign schwannomas which do not progress to malignancy and meningiomas
Entity name
sporadic meningioma
Entity name
sporadic schwannoma
Entity name
other tumours: ependymoma; mesothelioma
