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

Verdict is Likely_pathogenic. Variant got 9 ACMG points.

• 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, pituitary gigantism, familial isolated hyperparathyroidism.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.963
• PP5: Variant 11-64810075-G-A is Pathogenic according to our data. Variant chr11-64810075-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 200969.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr11-64810075-G-A is described in Lovd as [Pathogenic].

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 12 of the MEN1 protein (p.Pro12Leu). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with multiple endocrine neoplasia type 1 (PMID: 9215689, 31658439; internal data). ClinVar contains an entry for this variant (Variation ID: 200969). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt MEN1 protein function with a positive predictive value of 95%. Experimental studies have shown that this missense change affects MEN1 function (PMID: 12509449, 15254225, 21264250, 21819486, 22090276). For these reasons, this variant has been classified as Pathogenic. -
