Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 1P and 6B. PP2BP4BP6BS2

The NM_001370259.2(MEN1):c.1506G>C(p.Lys502Asn) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000144 in 1,599,226 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K502R) has been classified as Uncertain significance.

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]

Hereditary cancer-predisposing syndrome

Uncertain:1Benign:1

Benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Jan 25, 2022	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. -

Sep 22, 2022

The MEN1 c.1521G>C variant is predicted to result in the amino acid substitution p.Lys507Asn. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.032% of alleles in individuals of African descent in gnomAD (http://gnomad.broadinstitute.org/variant/11-64572133-C-G) and is interpreted as a variant of uncertain significance in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/403821/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
