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]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 5 ACMG points.

PM1
In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 2 benign, 26 uncertain in NM_001370259.2
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the MEN1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 113 curated pathogenic missense variants (we use a threshold of 10). The gene has 20 curated benign missense variants. Trascript score misZ: 4.1921 (above the threshold of 3.09). GenCC associations: The gene is linked to multiple endocrine neoplasia type 1, hereditary pheochromocytoma-paraganglioma, pituitary gigantism, familial isolated hyperparathyroidism.

Multiple endocrine neoplasia, type 1 Uncertain:1
Jul 03, 2024
Labcorp Genetics (formerly Invitae), Labcorp
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 290 of the MEN1 protein (p.Glu290Val). 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: 643563). 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
Apr 08, 2025
Ambry Genetics
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.E290V variant (also known as c.869A>T), located in coding exon 5 of the MEN1 gene, results from an A to T substitution at nucleotide position 869. The glutamic acid at codon 290 is replaced by valine, an amino acid with dissimilar properties. This variant was reported in individual(s) with features consistent with multiple endocrine neoplasia type 1 (Romanet P et al. Hum Mutat, 2019 Jun;40:661-674; Ambry internal data). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this alteration remains unclear. -
