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. -

not provided Uncertain:2Benign:1
- -
In silico analysis supports that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 29618661, 32150022, 23975423, 25931164, 25925381, 16983642, 15684865, 24728327) -
- -
Hereditary cancer-predisposing syndrome Uncertain:1Benign:1
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. -

NF2-related disorder Uncertain:1
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. -
