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:4

Uncertain significance, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Dec 04, 2018	The p.Thr528Met variant in POLE has not been previously reported in individuals with colorectal cancer but has been identified in 0.02% (30/128702) of European chromosomes by gnomAD (http://gnomad.broadinstitute.org). This variant has also been reported as a variant of uncertain significance in ClinVar (Variation ID 24 0397). Computational prediction tools and conservation analysis suggest that thi s variant may impact the protein, though this information is not predictive enou gh to determine pathogenicity. In summary, the clinical significance of the p.Th r528Met variant is uncertain. ACMG/AMP Criteria applied: PP3. -

Uncertain:3

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Feb 01, 2024	This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 528 of the POLE protein (p.Thr528Met). This variant is present in population databases (rs116263919, gnomAD 0.02%). 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: 240397). 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 expected to disrupt POLE protein function with a positive 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 submitter	clinical testing	ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	Sep 28, 2019	The POLE c.1583C>T; p.Thr528Met variant (rs116263919), to our knowledge, is not reported in the medical literature but is reported in ClinVar (Variation ID: 240397). This variant is found in the general population with an overall allele frequency of 0.01% (34/282088 alleles) in the Genome Aggregation Database. The threonine at codon 528 is moderately conserved, and computational analyses (SIFT, PolyPhen-2) predict that this variant is deleterious. Due to limited information, the clinical significance of this variant is uncertain at this time. -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Dec 16, 2024	In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 29338689, 35534704, 38773787) -

Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Dec 09, 2024	The p.T528M variant (also known as c.1583C>T), located in coding exon 15 of the POLE gene, results from a C to T substitution at nucleotide position 1583. The threonine at codon 528 is replaced by methionine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -

Mar 14, 2024

The POLE c.1583C>T variant is predicted to result in the amino acid substitution p.Thr528Met. This variant was reported in an individual with breast cancer (Park. 2018. PubMed ID: 29338689). This variant is reported in 0.023% of alleles in individuals of European (Non-Finnish) descent in gnomAD and is interpreted as uncertain in ClinVar by the majority of submitters (https://www.ncbi.nlm.nih.gov/clinvar/variation/240397/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
