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]

Submissions by phenotype
Multiple endocrine neoplasia, type 1 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jun 19, 2019 | For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in MEN1 are known to be pathogenic (PMID: 12112656, 17853334). This variant has been observed in individuals with multiple endocrine neoplasia type 1 (PMID: 10090472, 22470073). This variant is also known as c.1192C>T, p.Gln398Term in the literature. ClinVar contains an entry for this variant (Variation ID: 428027). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Gln393*) in the MEN1 gene. It is expected to result in an absent or disrupted protein product. - |
Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 20, 2013 | ​The p.Q393X pathogenic mutation (also known as c.1177C>T), located in coding exon 7 of the MEN1 gene, results from a C to T substitution at nucleotide position 1177. This changes the amino acid from a glutamine to a stop codon within coding exon 7. This mutation has been previously identified in multiple MEN1 kindreds (Pieterman, CR et al. Ann Surg. 2012 Jun;255(6):1171-8; Mutch, MG et al. Hum Mutat. 1999;13(3):175-85). In addition to the clinical data presented in the literature, since premature stop codons are typically deleterious in nature, this alteration is interpreted as a disease-causing mutation (ACMG Recommendations for Standards for Interpretation and Reporting of Sequence Variations. Revision 2007. Genet Med. 2008;10:294). This mutation is also called p.G398X (c.1192C>T) in published literature. - |
