Labcorp Genetics (formerly Invitae), Labcorp RCV002715526 SCV003001073 uncertain significance Neurofibromatosis, type 2 2022-09-20 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 552 of the NF2 protein (p.Lys552Arg). This variant has not been reported in the literature in individuals affected with NF2-related conditions. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt NF2 protein function.
All of Us Research Program, National Institutes of Health RCV002715526 SCV004832846 uncertain significance Neurofibromatosis, type 2 2023-04-10 criteria provided, single submitter clinical testing This missense variant replaces lysine with arginine at codon 552 of the NF2 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with NF2-related disorders in the literature. This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance.
