Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 3P and 6B. PM5PP2BP4_ModerateBS2

The NM_001370259.2(MEN1):c.1541C>G(p.Pro514Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000825 in 1,454,664 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P514?) has been classified as Pathogenic.

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 -3 ACMG points.

PM5

Other missense variant is known to change same aminoacid residue: Variant chr11-64804625-GGG-GC is described in Lovd as [Pathogenic].

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, pituitary gigantism, familial isolated hyperparathyroidism.

BP4

Computational evidence support a benign effect (MetaRNN=0.24450243).

BS2

High AC in GnomAdExome4 at 12 AD gene.

This missense variant replaces proline with arginine at codon 514 of the MEN1 protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has been reported in an individual affected with a pancreatic neuroendocrine tumor (PMID: 32451928). This variant has been identified in 1/236694 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. -

The c.1541C>G (p.P514R) alteration is located in exon 10 (coding exon 9) of the MEN1 gene. This alteration results from a C to G substitution at nucleotide position 1541, causing the proline (P) at amino acid position 514 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
