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]

The c.431_432delTCinsAA pathogenic mutation, located in coding exon 1 of the MEN1 gene, results from a deletion of TC and an insertion of AA at nucleotide positions 431 and 432. This changes the amino acid at codon 144 from a phenylalanine to a stop codon within coding exon 1. This mutation has been reported in a single individual from a cohort of 186 patients with either a clinical diagnosis or suspected diagnosis of multiple endocrine neoplasia type 1 (MEN1) (Ellard S et al. Clin Endocrinol (Oxf). 2005 Feb;62(2):169-75). 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). -
