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]

This missense variant replaces alanine with serine at codon 176 of the MEN1 protein. Computational prediction suggests that this variant may have deleterious impact on protein structure and function (internally defined REVEL score threshold >= 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been detected in 3 individuals or families affected with MEN1 (PMID: 30820182). A different missense variant at this codon, p.Ala176Pro, is considered disease-causing in ClinVar (variation ID 200975) and has been detected in a family affected with MEN1 (PMID: 9215689) and functional studies have shown the p.Ala176Pro variant to be unstable and exhibited loss of function in the binding and regulation of JunD and in homology-directed repair and response to DNA damage (PMID: 9989505, 11221882, 12509449, 22090276, 23648481). This variant has been identified in 5/251222 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
