Genes affected
MEN1 (HGNC:7010): (menin 1) This gene encodes menin, a tumor suppressor associated with a syndrome known as multiple endocrine neoplasia type 1. Menin is a scaffold protein that functions in histone modification and epigenetic gene regulation. It is thought to regulate several pathways and processes by altering chromatin structure through the modification of histones. [provided by RefSeq, May 2019]

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The MEN1 c.1397A>T; p.Glu466Val variant (rs1352053477), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 457293). This variant is absent from general population databases (Exome Variant Server, Genome Aggregation Database), indicating it is not a common polymorphism. The glutamate at codon 466 is moderately conserved, and computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.484). Due to limited information, the clinical significance of the p.Glu466Val variant is uncertain at this time. -

Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge; This variant is associated with the following publications: (PMID: 11274402, 11526476) -

Multiple endocrine neoplasia, type 1 Uncertain:1

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces glutamic acid, which is acidic and polar, with valine, which is neutral and non-polar, at codon 466 of the MEN1 protein (p.Glu466Val). 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: 457293). 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 with a positive predictive value of 80%. 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. -

Hereditary cancer-predisposing syndrome Uncertain:1

Ambry Genetics
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.E466V variant (also known as c.1397A>T), located in coding exon 9 of the MEN1 gene, results from an A to T substitution at nucleotide position 1397. The glutamic acid at codon 466 is replaced by valine, an amino acid with dissimilar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
