Variant summary
Our verdict is Pathogenic. The variant received 17 ACMG points: 17P and 0B. PM1PM2PM5PP2PP3_ModeratePP5_Very_Strong
The NM_001370259.2(MEN1):c.416A>G(p.His139Arg) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. H139Q) has been classified as Likely pathogenic.

Multiple endocrine neoplasia, type 1 Pathogenic:1
In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This variant disrupts the p.His139 amino acid residue in MEN1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 12746426, 21917868, 30324798). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt MEN1 protein function. ClinVar contains an entry for this variant (Variation ID: 428056). This missense change has been observed in individual(s) with clinical features of MEN1-related disease (PMID: 10617276, 30820182). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 139 of the MEN1 protein (p.His139Arg). -
Hereditary cancer-predisposing syndrome Pathogenic:1
The p.H139R pathogenic mutation (also known as c.416A>G), located in coding exon 1 of the MEN1 gene, results from an A to G substitution at nucleotide position 416. The histidine at codon 139 is replaced by arginine, an amino acid with highly similar properties. This alteration has been reported in one Spanish family diagnosed with MEN1 (Martín-Campos JM et al. Diagn Mol Pathol. 1999 Dec;8(4):195-204). Additionally, this variant has been confirmed as a de novo alteration in one family (Ambry internal data). This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. -
