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	Labcorp Genetics (formerly Invitae), Labcorp	Nov 08, 2023	This sequence change replaces phenylalanine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 63 of the MEN1 protein (p.Phe63Leu). This variant is not present in population databases (gnomAD no frequency). 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: 452316). 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. -

DNA sequence analysis of the MEN1 gene demonstrated a sequence change, c.189C>G, in exon 2 that results in an amino acid change, p.Phe63Leu. This sequence change has been described in the gnomAD database in a single heterozygous individual which corresponds to a population frequency of 0.0005% (dbSNP rs137880635). The p.Phe63Leu change affects a moderately conserved amino acid residue located in a domain of the MEN1 protein that is known to be functional. In-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL) provide contradictory results for the p.Phe63Leu substitution. This sequence change does not appear to have been previously described in individuals with MEN1-related disorders. Due to insufficient evidences and the lack of functional studies, the clinical significance of the p.Phe63Leu change remains unknown at this time. -

The MEN1 c.189C>G variant is predicted to result in the amino acid substitution p.Phe63Leu. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0084% of alleles in individuals of African descent in gnomAD. This variant is interpreted as uncertain in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/452316/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

The p.F63L variant (also known as c.189C>G), located in coding exon 1 of the MEN1 gene, results from a C to G substitution at nucleotide position 189. The phenylalanine at codon 63 is replaced by leucine, an amino acid with highly similar properties. This amino acid position is highly 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. -
