Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 5P and 1B. PM1 PM2 PP2 BP4

The NM_001370259.2(MEN1):​c.1061G>C​(p.Cys354Ser) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another nucleotide change resulting in same amino acid change has been previously reported as Uncertain significancein ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C354F) 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: 4.05

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 Uncertain_significance. Variant got 4 ACMG points.

• PM1: In a hotspot region, there are 5 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 12 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.
• BP4: Computational evidence support a benign effect (MetaRNN=0.4008109).
