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 MEN1 c.1391C>T; p.Ala464Val variant (rs778728934), to our knowledge, is not reported in the medical literature. The variant is listed in the ClinVar database (Variation ID: 403807) and is reported in the South Asian population with an allele frequency of 0.05% (14/30252 alleles) in the Genome Aggregation Database. The alanine at codon 464 is moderately conserved, and computational analyses (SIFT, PolyPhen-2) predict that this variant is tolerated. Due to limited information, the clinical significance of the p.Ala464Val variant is uncertain at this time. -

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
