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]

Variant summary: MEN1 c.1099G>A (p.Val367Ile) results in a conservative amino acid change in the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00013 in 251372 control chromosomes, predominantly at a frequency of 0.00087 within the Latino subpopulation in the gnomAD database. The observed variant frequency within Latino control individuals in the gnomAD database is approximately 41-fold of the estimated maximal expected allele frequency for a pathogenic variant in MEN1 causing Multiple Endocrine Neoplasia Type 1 phenotype (2.1e-05). c.1099G>A has been reported in the literature in individuals affected with Multiple Endocrine Neoplasia Type 1, without strong evidence for causality (Christakis_2018). This report does not provide unequivocal conclusions about association of the variant with Multiple Endocrine Neoplasia Type 1. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publication has been ascertained in the context of this evaluation (PMID: 29122330). ClinVar contains an entry for this variant (Variation ID: 403848). Based on the evidence outlined above, the variant was classified as likely benign. -

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely 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. -
