• NM_001370259.2:c.115T>A

Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2 PM5 PP2 PP3

The NM_001370259.2(MEN1):​c.115T>A​(p.Leu39Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L39W) has been classified as Likely pathogenic.

• Frequency: Genomes: not found (cov: 31)
• Consequence: MEN1 NM_001370259.2 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 1.42

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 Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chrnull-null-null-null is described in UniProt as null.
• 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.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.788
