Genes affected
NF2 (HGNC:7773): (NF2, moesin-ezrin-radixin like (MERLIN) tumor suppressor) This gene encodes a protein that is similar to some members of the ERM (ezrin, radixin, moesin) family of proteins that link cytoskeletal components with proteins in the cell membrane. The encoded protein is involved in regulation of contact-dependent inhibition of cell proliferation and functions in cell-cell adhesion and transmembrane signaling. The encoded protein has been shown to interact with cell-surface proteins, proteins involved in cytoskeletal dynamics, and proteins involved in regulating ion transport. Disruption of this protein's function has been implicated in tumorigenesis and metastasis. Mutations in this gene are associated with neurofibromatosis type II which is characterized by nervous system and skin tumors and ocular abnormalities. [provided by RefSeq, May 2022]

The NF2 c.107A>G (p.Asn36Ser) missense change has a maximum subpopulation frequency of 0.029% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL predicts a benign effect on protein function, but to our knowledge this prediction has not been confirmed by functional studies. This variant has been reported in an individual with a vestibular schwannoma (PMID: 15684865). In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. -

Significance: Likely benign
Review Status: criteria provided, single submitter

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

The NF2 c.107A>G variant is predicted to result in the amino acid substitution p.Asn36Ser. This variant was previously described in one individual who presented with suspected neurofibromatosis type 2 (Wallace et al. 2004. PubMed ID: 15684865) and in a patient with a mild form of vestibular schwannomas (Heineman et al. 2015. PubMed ID: 25931164). However, this variant has also been reported in a cohort of presumably healthy individuals (Table S1 - Bodian et al. 2014. PubMed ID: 24728327). This variant is reported in 0.016% of alleles in individuals of East Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/22-30000094-A-G) and has conflicting interpretations regarding its pathogenicity in ClinVar, ranging from benign to uncertain (https://www.ncbi.nlm.nih.gov/clinvar/variation/134892/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
