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 variant has been observed in individual(s) with multiple endocrine neoplasia type 1 (PMID: 29497973). ClinVar contains an entry for this variant (Variation ID: 527239). This variant is present in population databases (rs761102084, ExAC 0.006%). This sequence change replaces proline with arginine at codon 390 of the MEN1 protein (p.Pro390Arg). The proline residue is weakly conserved and there is a moderate physicochemical difference between proline and arginine. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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. -

The p.P390R variant (also known as c.1169C>G), located in coding exon 7 of the MEN1 gene, results from a C to G substitution at nucleotide position 1169. The proline at codon 390 is replaced by arginine, an amino acid with dissimilar properties. This amino acid position is not 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. -
