Genes affected

POLE (HGNC:9177): (DNA polymerase epsilon, catalytic subunit) This gene encodes the catalytic subunit of DNA polymerase epsilon. The enzyme is involved in DNA repair and chromosomal DNA replication. Mutations in this gene have been associated with colorectal cancer 12 and facial dysmorphism, immunodeficiency, livedo, and short stature. [provided by RefSeq, Sep 2013]

Collection Method: clinical testing

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 697 of the POLE protein (p.Pro697Leu). This variant is present in population databases (rs36120395, gnomAD 0.008%). 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: 405654). 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. -

The p.Pro697Leu variant in POLE has not been previously reported in individuals with colorectal cancer, but has been identified in 1/11552 of Latino chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSN P rs36120395). Computational prediction tools and conservation analysis do not p rovide strong support for or against an impact to the protein. In summary, the c linical significance of the p.Pro697Leu variant is uncertain. -

The POLE c.2090C>T variant is predicted to result in the amino acid substitution p.Pro697Leu. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0078% of alleles in individuals of European (Non-Finnish) descent in gnomAD and is interpreted as uncertain significance (https://www.ncbi.nlm.nih.gov/clinvar/variation/405654/?new_evidence=true). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
