Ambry Genetics	RCV002338489	SCV002643752	uncertain significance	Hereditary cancer-predisposing syndrome	2022-06-05	criteria provided, single submitter	clinical testing	The p.L339R variant (also known as c.1016T>G), located in coding exon 11 of the NF2 gene, results from a T to G substitution at nucleotide position 1016. The leucine at codon 339 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
All of Us Research Program, National Institutes of Health	RCV004005683	SCV004828997	uncertain significance	Neurofibromatosis, type 2	2023-06-08	criteria provided, single submitter	clinical testing	This missense variant replaces leucine with arginine at codon 339 of the NF2 protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, 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.
