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]

Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Jan 28, 2024	This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 489 of the MEN1 protein (p.Pro489Ser). This variant is present in population databases (rs587778440, gnomAD 0.003%). 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: 134641). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on MEN1 protein function. 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. -
Uncertain significance, criteria provided, single submitter	clinical testing	All of Us Research Program, National Institutes of Health	May 16, 2023	This missense variant replaces proline with serine at codon 489 of the MEN1 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with MEN1-related disorders in the literature. This variant has been identified in 1/216848 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. -

Ambry Genetics

Oct 24, 2022

The p.P489S variant (also known as c.1465C>T), located in coding exon 9 of the MEN1 gene, results from a C to T substitution at nucleotide position 1465. The proline at codon 489 is replaced by serine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
