Ambry Genetics RCV000569105 SCV000674146 uncertain significance Hereditary cancer-predisposing syndrome 2018-08-23 criteria provided, single submitter clinical testing The p.M529T variant (also known as c.1586T>C), located in coding exon 15 of the NF2 gene, results from a T to C substitution at nucleotide position 1586. The methionine at codon 529 is replaced by threonine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
Invitae RCV000703849 SCV000832773 uncertain significance Neurofibromatosis, type 2 2020-10-12 criteria provided, single submitter clinical testing This sequence change replaces methionine with threonine at codon 529 of the NF2 protein (p.Met529Thr). The methionine residue is moderately conserved and there is a moderate physicochemical difference between methionine and threonine. This variant is present in population databases (rs780818183, ExAC 0.009%). This variant has not been reported in the literature in individuals with NF2-related disease. ClinVar contains an entry for this variant (Variation ID: 485982). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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.
