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]

For these reasons, this variant has been classified as Pathogenic. This deletion removes the functionally conserved nuclear localization signal of the MEN1 protein. Experimental studies have shown that disruption of this region abrogates the ability of MEN1 to bind DNA, regulate target gene expression, and inhibit cell proliferation (PMID: 15331604, 16449969). Similar deletions of exon 10 of the MEN1 gene have been reported in an individual affected with multiple endocrine neoplasia type 1 (Invitae) and individuals in the Universal Mutation Database (PMID: 10612827). This variant is a gross deletion of the genomic region encompassing exon 10 of the MEN1 gene. The 5' boundary is located at c.1351-2 and the 3' end of this event is located at c.*132. While this deletion is not anticipated to result in nonsense mediated decay, it is expected to create a truncated protein product. -
