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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.34).

Clinvar id is 215966.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Benign=3, Likely_benign=9}. Variant chr11-64807573-C-T is described in Lovd as [Likely_benign].
• BP7: Synonymous conserved (PhyloP=0.929 with no splicing effect.
• BS1: Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.000215 (315/1461856) while in subpopulation MID AF= 0.00104 (6/5768). AF 95% confidence interval is 0.000453. There are 0 homozygotes in gnomad4_exome. There are 170 alleles in male gnomad4_exome subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 27 AD gene.

Benign, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Apr 27, 2017	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases was too high to be consistent with this variant causing disease. Therefore, this variant is classified as benign. -

Apr 27, 2017

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
