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 was made for transcript

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

PM1
In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 3 benign, 35 uncertain in NM_001370259.2
PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the MEN1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 113 curated pathogenic missense variants (we use a threshold of 10). The gene has 20 curated benign missense variants. Trascript score misZ: 4.1921 (above the threshold of 3.09). GenCC associations: The gene is linked to multiple endocrine neoplasia type 1, hereditary pheochromocytoma-paraganglioma, pituitary gigantism, familial isolated hyperparathyroidism.
BP6
Variant 11-64810039-G-A is Benign according to our data. Variant chr11-64810039-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 527250.

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.A24V variant (also known as c.71C>T), located in coding exon 1 of the MEN1 gene, results from a C to T substitution at nucleotide position 71. The alanine at codon 24 is replaced by valine, an amino acid with similar 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. -
