ClinVar
Submissions by phenotype
not provided Uncertain:2
This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 1580 of the POLE protein (p.Arg1580Gln). This variant is present in population databases (rs201950040, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with POLE-related conditions. ClinVar contains an entry for this variant (Variation ID: 540738). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt POLE protein function with a negative predictive value of 80%. 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. -
In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
POLE-related disorder Uncertain:1
The POLE c.4739G>A variant is predicted to result in the amino acid substitution p.Arg1580Gln. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.011% of alleles in individuals of East Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/12-133219305-C-T) and is interpreted as uncertain significance in ClinVar (https://preview.ncbi.nlm.nih.gov/clinvar/variation/540738/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
Hereditary cancer-predisposing syndrome Uncertain:1
The p.R1580Q variant (also known as c.4739G>A), located in coding exon 37 of the POLE gene, results from a G to A substitution at nucleotide position 4739. The arginine at codon 1580 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. Based on the available evidence, the clinical significance of this variant remains unclear. -
