Variant summary

Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PM2 PM5 PP2 PP3_Strong PP5_Moderate

The NM_001370259.2(MEN1):​c.1252G>T​(p.Asp418Tyr) 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 Pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D418G) 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

Verdict is Pathogenic. Variant got 11 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr11-64805131-T-C 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, 0.958
• PP5: Variant 11-64805132-C-A is Pathogenic according to our data. Variant chr11-64805132-C-A is described in ClinVar as [Pathogenic]. Clinvar id is 428083.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr11-64805132-C-A is described in Lovd as [Pathogenic].

The p.D418Y pathogenic mutation (also known as c.1252G>T), located in coding exon 8 of the MEN1 gene, results from a G to T substitution at nucleotide position 1252. The aspartic acid at codon 418 is replaced by tyrosine, an amino acid with highly dissimilar properties. This alteration has been observed in multiple individuals with a personal history that is consistent with MEN1-related disease (Ozturk M et al. J Endocrinol Invest. 2006 Jun;29(6):523-7; Ambry internal data). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. -
