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 18 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 11-64809764-C-A is Pathogenic according to our data. Variant chr11-64809764-C-A is described in ClinVar as [Pathogenic]. Clinvar id is 403842.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr11-64809764-C-A is described in Lovd as [Pathogenic].

Multiple endocrine neoplasia, type 1 Pathogenic:1

Nov 18, 2016

Labcorp Genetics (formerly Invitae), Labcorp

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Loss-of-function variants in MEN1 are known to be pathogenic. This particular variant has been reported in the literature in individuals affected with multiple endocrine neoplasia type 1 (PMID: 17235589). For these reasons, this variant has been classified as Pathogenic. This sequence change creates a premature translational stop signal at codon 116 (p.Glu116*) of the MEN1 gene. It is expected to result in an absent or disrupted protein product. -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.E116* pathogenic mutation (also known as c.346G>T), located in coding exon 1 of the MEN1 gene, results from a G to T substitution at nucleotide position 346. This changes the amino acid from a glutamic acid to a stop codon within coding exon 1. This alteration has been reported in four individuals with multiple endocrine neoplasia type 1 (MEN1), all of whom were reported to have non-functioning adrenal tumors (Waldmann J et al. Langenbecks Arch Surg, 2007 Jul;392:437-43). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. -
