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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -4 ACMG points.

PP2

Missense variant in the MEN1 gene, where missense mutations are typically associated with disease (based on misZ statistic).

Collection Method: clinical testing

The MEN1 c.16G>T (p.Ala6Ser) missense change has a maximum population frequency of 0.0079% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/). The in silico tool REVEL is inconclusive about a pathogenic or benign effect of this variant on protein function, and to our knowledge functional studies have not been performed. To our knowledge, this variant has not been reported in individuals with multiple endocrine neoplasia type I or MEN1-associated tumors. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. -

The p.A6S variant (also known as c.16G>T), located in coding exon 1 of the MEN1 gene, results from a G to T substitution at nucleotide position 16. The alanine at codon 6 is replaced by serine, an amino acid with similar properties. In one study, which performed structural analysis for MEN1 missense variants, this alteration did not meet the threshold for pathogenicity (Caswell RC et al. J Endocr Soc, 2019 Dec;3:2258-2275). 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. -
