Description

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. 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: 946791). This variant has not been reported in the literature in individuals affected with MEN1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces methionine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 234 of the MEN1 protein (p.Met234Leu).
