Invitae RCV001224295 SCV001396483 uncertain significance Multiple endocrine neoplasia, type 1 2023-07-25 criteria provided, single submitter clinical testing 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 expected to disrupt MEN1 protein function. ClinVar contains an entry for this variant (Variation ID: 952229). This variant has not been reported in the literature in individuals affected with MEN1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 17 of the MEN1 protein (p.Asp17Gly).
Ambry Genetics RCV003380903 SCV004091389 uncertain significance Hereditary cancer-predisposing syndrome 2023-07-27 criteria provided, single submitter clinical testing The p.D17G variant (also known as c.50A>G), located in coding exon 1 of the MEN1 gene, results from an A to G substitution at nucleotide position 50. The aspartic acid at codon 17 is replaced by glycine, an amino acid with similar 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.
