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 submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 31, 2024	This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 685 of the POLE protein (p.Arg685Trp). This variant is present in population databases (rs116326665, gnomAD 0.03%). 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: 405614). 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. -

The POLE p.Arg685Trp variant was not identified in the literature. The variant was identified in dbSNP (ID: rs116326665) as "With Uncertain significance allele", and in ClinVar (classified as uncertain significance by Invitae). The variant was identified in control databases in 18 of 269702 chromosomes at a frequency of 0.00007 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 1 of 23964 chromosomes (freq: 0.00004), European in 2 of 123376 chromosomes (freq: 0.00002), East Asian in 6 of 18674 chromosomes (freq: 0.0003), and South Asian in 9 of 29240 chromosomes (freq: 0.0003); it was not observed in the Other, Latino, Ashkenazi Jewish, and Finnish, populations. The p.Arg685 residue is conserved in mammals but not in more distantly related organisms, and four out of five computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) suggest that the variant may impact the protein; however, this information is not predictive enough to assume pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
