Variant summary
Our verdict is Likely pathogenic. Variant got 7 ACMG points: 7P and 0B. PM2PP2PP3_Strong
The NM_001370259.2(MEN1):c.236C>T(p.Pro79Leu) variant causes a missense change involving the alteration of a conserved nucleotide. 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 Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P79R) has been classified as Uncertain significance.

Multiple endocrine neoplasia, type 1 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jul 25, 2022 | 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: 649241). This variant has not been reported in the literature in individuals affected with MEN1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 79 of the MEN1 protein (p.Pro79Leu). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jul 15, 2022 | The p.P79L variant (also known as c.236C>T), located in coding exon 1 of the MEN1 gene, results from a C to T substitution at nucleotide position 236. The proline at codon 79 is replaced by leucine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
