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]

Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -

The POLE p.Tyr187= variant was not identified in the literature. The variant was identified in dbSNP (rs143938822) as “with likely benign allele” and ClinVar (classified as likely benign by Ambry Genetics, GeneDx, PreventionGenetics and Quest Diagnostics and Benign by Invitae and 1 other submitter). The variant was identified in control databases in 60 of 282,732 chromosomes at a frequency of 0.0002 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: Ashkenazi Jewish in 13 of 10,366 chromosomes (freq: 0.001), Other in 2 of 7222 chromosomes (freq: 0.0003), European in 35 of 129,070 chromosomes (freq: 0.0003), Latino in 7 of 35,426 chromosomes (freq: 0.0002), African in 3 of 24,966 chromosomes (freq: 0.0001), while the variant was not observed in the East Asian, Finnish and South Asian populations. The p.Tyr187= variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site. The variant occurs at a non-highly conserved nucleotide 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 although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
