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.

• PM2: Very rare variant in population databases, with high coverage
• PM4: Nonframeshift variant in NON repetitive region in NM_001370259.2.

Variant summary: MEN1 c.119_124delTGCTGG (p.Val40_Leu41del) results in an in-frame deletion that is predicted to remove two amino acids (Val, Leu) from the encoded protein. The variant was absent in 217338 control chromosomes (in gnomAD). The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.119_124delTGCTGG in individuals affected with Multiple Endocrine Neoplasia Type 1 and no experimental evidence demonstrating its impact on protein function have been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as uncertain significance. -

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Experimental studies and prediction algorithms are not available for this variant, and the functional significance of the deleted amino acids is currently unknown. This variant has been observed in an individual affected with multiple endocrine neoplasia type 1 (PMID: 26767918). ClinVar contains an entry for this variant (Variation ID: 36522). This variant is not present in population databases (ExAC no frequency). This variant, c.119_124delTGCTGG, results in the deletion of 2 amino acid(s) of the MEN1 protein (p.Val40_Leu41del), but otherwise preserves the integrity of the reading frame. -
