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:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Oct 13, 2023 | This sequence change affects a donor splice site in intron 9 of the MEN1 gene. While this variant is not anticipated to result in nonsense mediated decay, it likely alters RNA splicing and results in a disrupted protein product. This variant is not present in population databases (gnomAD no frequency). Disruption of this splice site has been observed in individual(s) with multiple endocrine neoplasia type 1 (PMID: 25309785). ClinVar contains an entry for this variant (Variation ID: 457287). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. This variant disrupts a region of the MEN1 protein in which other variant(s) (p.Ser555Asn) have been determined to be pathogenic (PMID: 9683585, 15254225, 21819486). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. - |
