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

The p.Met2086Thr variant in POLE has not been previously reported in the literat ure in individuals with colorectal cancer but has been reported in ClinVar (Vari ation ID 240588). This variant has also been identified in 1/66718 of European c hromosomes and 1/8652 of East Asian chromosomes by the Exome Aggregation Consort ium (ExAC, http://exac.broadinstitute.org; dbSNP rs528752399). Computational pre diction tools and conservation analysis do not provide strong support for or aga inst an impact to the protein. In summary, the clinical significance of the p.Me t2086Thr variant is uncertain. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces methionine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 2086 of the POLE protein (p.Met2086Thr). This variant is present in population databases (rs528752399, gnomAD 0.006%). 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: 240588). 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 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. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Not observed at a significant frequency in large population cohorts (Lek et al., 2016); In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -

Review Status: criteria provided, single submitter

Collection Method: research

Found in patient having exome sequencing due to suspicion for hereditary colon cancer and/or polyps. Patient is a 43 year old male with a history of colon cancer diagnosed at age 26. This interpretation considers GERP score and allele frequency data, in addition to published reports of the variant in the literature, available at the time of review. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.M2086T variant (also known as c.6257T>C), located in coding exon 45 of the POLE gene, results from a T to C substitution at nucleotide position 6257. The methionine at codon 2086 is replaced by threonine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
