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 Uncertain_significance. Variant got 5 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the MEN1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 113 curated pathogenic missense variants (we use a threshold of 10). The gene has 20 curated benign missense variants. Trascript score misZ: 4.1921 (above the threshold of 3.09). GenCC associations: The gene is linked to multiple endocrine neoplasia type 1, pituitary gigantism, familial isolated hyperparathyroidism.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.914

The p.S104Y variant (also known as c.311C>A), located in coding exon 1 of the MEN1 gene, results from a C to A substitution at nucleotide position 311. The serine at codon 104 is replaced by tyrosine, an amino acid with dissimilar properties. The p.L34M variant (also known as c.100C>A), located in coding exon 1 of the MEN1 gene, results from a C to A substitution at nucleotide position 100. The leucine at codon 34 is replaced by methionine, an amino acid with highly similar properties. The p.S104Y and p.L34M variants have been observed in cis in individuals with features consistent with multiple endocrine neoplasia type 1 (Ambry internal data). These amino acid positions are highly conserved in available vertebrate species. In addition, these variants predicted to be deleterious by in silico analysis. These variants are considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). Based on the majority of available evidence to date, the p.S104Y and p.L34M variants are interpreted as a likely pathogenic haplotype. -
