Submissions by phenotype
Multiple endocrine neoplasia, type 1 Uncertain:1
This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 335 of the MEN1 protein (p.Arg335Gln). This variant is present in population databases (rs764998893, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with MEN1-related conditions. ClinVar contains an entry for this variant (Variation ID: 403817). 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 with a positive predictive value of 95%. 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
The p.R335Q variant (also known as c.1004G>A), located in coding exon 6 of the MEN1 gene, results from a G to A substitution at nucleotide position 1004. The arginine at codon 335 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
