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


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


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 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 sporadic meningioma
Entity sporadic schwannoma
Entity other tumours: ependymoma; mesothelioma
