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]

Labcorp Genetics (formerly Invitae), Labcorp

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 1932 of the POLE protein (p.Arg1932His). This variant is present in population databases (rs778190944, gnomAD 0.009%). 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: 405889). 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. -

Ambry Genetics

Significance: Likely benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The missense variant NM_006231.4(POLE):c.5795G>A (p.Arg1932His) has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. There is a small physicochemical difference between arginine and histidine, which is not likely to impact secondary protein structure as these residues share similar properties. For these reasons, this variant has been classified as Uncertain Significance. -

PreventionGenetics, part of Exact Sciences

Significance: Uncertain significance

Review Status: no assertion criteria provided

Collection Method: clinical testing

The POLE c.5795G>A variant is predicted to result in the amino acid substitution p.Arg1932His. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0087% of alleles in individuals of Latino descent in gnomAD. This variant has an interpretation of uncertain significance in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/405889/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
