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]

Multiple endocrine neoplasia, type 1 Pathogenic:3
Pathogenic, criteria provided, single submitter | clinical testing | All of Us Research Program, National Institutes of Health | Jun 08, 2023 | This variant causes a 11-basepair deletion in intron 9 of the MEN1 gene, abolishing the intron 9 splice donor site. Splice site prediction tools predict that this variant may have a significant impact on RNA splicing. To our knowledge, functional studies have not been reported for this variant. This variant has been detected in multiple individuals affected with MEN1 and (primary hyperparathyroidism (PMID: 10090472, 16563611, 17065424, 27846313, 30324798). This variant has not been identified in the general population by the Genome Aggregation Database (gnomAD). Loss of MEN1 function is a known mechanism of disease (clinicalgenome.org). Based on the available evidence, this variant is classified as Pathogenic. - |
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Sep 03, 2023 | For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 201001). Disruption of this splice site has been observed in individuals with multiple endocrine neoplasia, type 1 (PMID: 9709921, 10090472). This variant is not present in population databases (gnomAD no frequency). This sequence change affects a splice site in intron 9 of the MEN1 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in MEN1 are known to be pathogenic (PMID: 12112656, 17853334). - |
Pathogenic, criteria provided, single submitter | clinical testing | Color Diagnostics, LLC DBA Color Health | Apr 18, 2023 | This variant causes a 11-basepair deletion in intron 9 of the MEN1 gene, abolishing the intron 9 splice donor site.

not provided Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | GeneDx | May 21, 2014 | The c.1350+1_1350+11delGTGAGGGACAG splice site mutation in the MEN1 gene has been previously reported in association with multiple endocrine neoplasia type 1 (Mutch et al., 1999). Using capital letters to denote exonic sequence and lower case letters to denote intronic sequence, the normal sequence with the bases that are deleted in braces is: ACAG{del gtgagggacag}ctgc. This mutation destroys the canonical splice donor site in intron 9, and is expected to cause abnormal gene splicing. The variant is found in MEN1 panel(s). - |
Hereditary cancer-predisposing syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Mar 14, 2024 | The c.1350+1_1350+11del11 intronic pathogenic mutation, located in intron 8 of the MEN1 gene, results from a deletion of 11 nucleotides within intron 8 of the MEN1 gene. This alteration has been seen in multiple unrelated families with clinical diagnoses and features of MEN1 (Teh BT et al. J. Clin. Endocrinol. Metab.1998 Aug;83:2621-6; Jäger AC et al. Mol. Cell. Endocrinol. 2006 Apr;249:123-32; Kong J. PLoS ONE. 2016 Nov;11(11):e0166634). This nucleotide region is well conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will weaken the native splice donor site and will result in the creation or strengthening of a novel splice donor site. This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). In addition to the clinical data presented in the literature, alterations that disrupt the canonical splice site are expected to cause aberrant splicing, resulting in an abnormal protein or a transcript that is subject to nonsense-mediated mRNA decay. As such, this alteration is classified as a disease-causing mutation. - |
