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]

DNA sequence analysis of the POLE gene demonstrated a sequence change, c.2510T>C, in exon 22 that results in an amino acid change, p.Phe837Ser. This sequence change does not appear to have been previously described in patients with POLE-related disorders and has been described in the gnomAD database with a frequency of 0.45% in the Ashkenazi Jewish sub-population (dbSNP rs139182500). The p.Phe837Ser change affects a moderately conserved amino acid residue located in a domain of the POLE protein that is known to be functional. In-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL) provide contradictory results for the p.Phe837Ser substitution. Due to these contrasting evidences and the lack of functional studies, the clinical significance of the p.Phe837Ser change remains unknown at this time.

Collection Method:clinical testing

The p.F837S variant (also known as c.2510T>C), located in coding exon 22 of the POLE gene, results from a T to C substitution at nucleotide position 2510. The phenylalanine at codon 837 is replaced by serine, an amino acid with highly dissimilar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear.

The POLE p.Phe837Ser variant was identified in 1 of 2080 proband chromosomes (frequency: 0.0005) from an individual with an unspecified cancer (Mandelker 2017). The variant was identified in dbSNP (rs139182500) as “with uncertain significance allele” and ClinVar (interpreted as "uncertain signficance" by Ambry Genetics and 2 others and "likely benign" by Invitae). The variant was identified in control databases in 72 of 277,116 chromosomes at a frequency of 0.0003 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: Other in 3 of 6462 chromosomes (freq: 0.0005), Latino in 10 of 34,420 chromosomes (freq: 0.0003), European in 16 of 126,680 chromosomes (freq: 0.0001), Ashkenazi Jewish in 43 of 10,150 chromosomes (freq: 0.004); it was not observed in the African, East Asian, Finnish, and South Asian populations. The p.Phe837 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of 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.
