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]

Uncertain significance, criteria provided, single submitterclinical testingGeneDxSep 23, 2024In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Observed in individuals with cutaneous melanoma and other cancers (PMID: 29641532); This variant is associated with the following publications: (PMID: 29572003, 29641532) -
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 30, 2024This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 1382 of the POLE protein (p.Arg1382His). This variant is present in population databases (rs143229302, gnomAD 0.02%). This missense change has been observed in individual(s) with melanoma (PMID: 29641532). ClinVar contains an entry for this variant (Variation ID: 405766). 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. -

Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsJul 30, 2024This 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. -
