Variant summary
Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PM2PM5PP2PP3_Strong
The NM_001370259.2(MEN1):c.502C>G(p.Leu168Val) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L168P) 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_pathogenic. Variant got 9 ACMG points.
PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chr11-64808042-A-G is described in Lovd as [Pathogenic].
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), MEN1. . Trascript score misZ 4.1921 (greater than threshold 3.09). GenCC has associacion of gene with multiple endocrine neoplasia type 1, pituitary gigantism, familial isolated hyperparathyroidism.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.966

Multiple endocrine neoplasia, type 1 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Oct 29, 2023 | This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 168 of the MEN1 protein (p.Leu168Val). 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: 527249). 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 with a positive predictive value of 95%. 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. - |
