Variant summary

Our verdict is Likely pathogenic. Variant got 7 ACMG points: 7P and 0B. PM1 PM2 PP2 PP3_Moderate

The NM_001370259.2(MEN1):​c.1226G>T​(p.Cys409Phe) 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. 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. C409Y) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: MEN1 NM_001370259.2 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 3.96

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 7 ACMG points.

• PM1: In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 14 uncertain in NM_001370259.2
• PM2: Very rare variant in population databases, with high coverage
• 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, 0.936
