In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge; This variant is associated with the following publications: (PMID: 20951805) -

This sequence change replaces serine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 925 of the POLE protein (p.Ser925Pro). This variant is present in population databases (rs141552148, 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: 240444). 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. -

not specified Uncertain:2
DNA sequence analysis of the POLE gene demonstrated a sequence change, c.2773T>C, in exon 24 that results in an amino acid change, p.Ser925Pro. This sequence change does not appear to have been previously described in patients with POLE-related disorders and has been described in the gnomAD database with a low population frequency of 0.0060% (dbSNP rs141552148). The p.Ser925Pro change affects a highly conserved amino acid residue located in a domain of the POLE protein that is known to be functional. In-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL) provide contradictory results for the p.Ser925Pro substitution. Due to these contrasting evidences and the lack of functional studies, the clinical significance of the p.Ser925Pro change remains unknown at this time. -

Hereditary cancer-predisposing syndrome Uncertain:1
The p.S925P variant (also known as c.2773T>C), located in coding exon 24 of the POLE gene, results from a T to C substitution at nucleotide position 2773. The serine at codon 925 is replaced by proline, an amino acid with similar properties. This amino acid position is well 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. -
