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 is present in population databases (rs371503251, gnomAD 0.002%). 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. 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: 485720). This variant has not been reported in the literature in individuals affected with MEN1-related conditions. This sequence change replaces cysteine, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 354 of the MEN1 protein (p.Cys354Arg). -

The p.C354R variant (also known as c.1060T>C), located in coding exon 7 of the MEN1 gene, results from a T to C substitution at nucleotide position 1060. The cysteine at codon 354 is replaced by arginine, an amino acid with highly dissimilar 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. -
