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 serine, which is neutral and polar, at codon 2091 of the POLE protein (p.Pro2091Ser). This variant is present in population databases (rs572252265, gnomAD 0.06%). 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: 473789). 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. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The missense c.6271C>T p.Pro2091Ser variant in the POLE gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. The variant is novel not in any individuals in gnomAD Exomes and 1000 Genom This variant is reported with the allele frequency 0.007% in the gnomAD Exomes and novel in 1000 Genomes. This variant has been reported to the ClinVar database as Uncertain Significance. However, no details are available for independent assessment. The amino acid Proline at position 2091 is changed to a Serine changing protein sequence and it might alter its composition and physico-chemical properties. The amino acid change p.Pro2091Ser in POLE is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. For these reasons, this variant has been classified as Uncertain Significance. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.P2091S variant (also known as c.6271C>T), located in coding exon 45 of the POLE gene, results from a C to T substitution at nucleotide position 6271. The proline at codon 2091 is replaced by serine, an amino acid with 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. -
