Variant summary

Our verdict is Pathogenic. Variant got 17 ACMG points: 17P and 0B. PM2 PM5 PP2 PP3_Strong PP5_Very_Strong

The NM_001370259.2(MEN1):​c.1306T>C​(p.Trp436Arg) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. W436C) has been classified as Pathogenic.

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 Pathogenic. Variant got 17 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr11-64805076-C-A is described in Lovd as [Pathogenic].
• 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, 0.99
• PP5: Variant 11-64805078-A-G is Pathogenic according to our data. Variant chr11-64805078-A-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 428003.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr11-64805078-A-G is described in Lovd as [Pathogenic]. Variant chr11-64805078-A-G is described in Lovd as [Pathogenic].

Labcorp Genetics (formerly Invitae), Labcorp

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant is not present in population databases (gnomAD no frequency). For these reasons, this variant has been classified as Pathogenic. 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: 428003). This missense change has been observed in individual(s) with hyperparathyroidism (PMID: 21127195, 21819486; Invitae). This sequence change replaces tryptophan, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 436 of the MEN1 protein (p.Trp436Arg). -
