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 arginine, which is basic and polar, with histidine, which is basic and polar, at codon 1579 of the POLE protein (p.Arg1579His). This variant is present in population databases (rs375590443, 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: 240539). 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 POLE c.4736G>A variant is predicted to result in the amino acid substitution p.Arg1579His. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.016% of alleles in individuals of South Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/12-133219308-C-T). This change has been documented as a variant of uncertain significance by multiple labs in the ClinVar database (https://www.ncbi.nlm.nih.gov/clinvar/variation/240539/evidence/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

Ambry Genetics
Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.4736G>A (p.R1579H) alteration is located in exon 37 (coding exon 37) of the POLE gene. This alteration results from a G to A substitution at nucleotide position 4736, causing the arginine (R) at amino acid position 1579 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
