Invitae RCV000709161 SCV000962724 uncertain significance Multiple endocrine neoplasia, type 1 2023-10-13 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 115 of the MEN1 protein (p.Arg115Gly). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MEN1-related conditions. ClinVar contains an entry for this variant (Variation ID: 584772). 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 expected to disrupt MEN1 protein function. 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.
Ambry Genetics RCV001020310 SCV001181771 uncertain significance Hereditary cancer-predisposing syndrome 2022-07-13 criteria provided, single submitter clinical testing The p.R115G variant (also known as c.343C>G), located in coding exon 1 of the MEN1 gene, results from a C to G substitution at nucleotide position 343. The arginine at codon 115 is replaced by glycine, an amino acid with dissimilar properties. This amino acid position is highly conserved in available vertebrate species. 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.
