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 testingInvitaeDec 15, 2023This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 77 of the POLE protein (p.Arg77Cys). This variant is present in population databases (no rsID available, gnomAD 0.003%). This missense change has been observed in individual(s) with early-onset colorectal cancer (PMID: 28195393). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 405896). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on POLE protein function. 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. -
