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

Our verdict: Likely_benign. The variant received -3 ACMG points.

• 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, hereditary pheochromocytoma-paraganglioma, pituitary gigantism, familial isolated hyperparathyroidism.
• BS2: High AC in GnomAdExome4 at 15 AD gene.
