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 testingInvitaeJan 06, 2024This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 259 of the POLE protein (p.Arg259Cys). This variant is present in population databases (rs777638541, gnomAD 0.007%). This missense change has been observed in individual(s) with cutaneous malignant melanoma (PMID: 26251183). ClinVar contains an entry for this variant (Variation ID: 371930). 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. -
Uncertain significance, criteria provided, single submitterclinical testingGeneDxSep 11, 2023Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Observed in an individual with a personal history of cutaneous malignant melanoma (Aoude et al., 2015); This variant is associated with the following publications: (PMID: 29120461, 26251183) -
