This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 1364 of the POLE protein (p.Arg1364Cys). This variant is present in population databases (rs770024304, gnomAD 0.02%). 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: 405621). 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 expected to disrupt POLE protein function with a positive 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 has a deleterious effect on protein structure/function; Observed in individual(s) with breast cancer (PMID: 28569218); This variant is associated with the following publications: (PMID: 29056344, 28569218) -
not specified Uncertain:1
The p.Arg1364Cys variant in POLE has not been previously reported in individuals with colorectal cancer, but has been identified in 1/66324 of European chromoso mes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; d bSNP rs770024304). Computational prediction tools and conservation analysis sugg est that the p.Arg1364Cys variant may impact the protein, though this informatio n is not predictive enough to determine pathogenicity. In summary, the clinical significance of the p.Arg1364Cys variant is uncertain. -
