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]

Significance:Likely benign
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.Phe1708= variant was not identified in the literature. The variant was identified in dbSNP (ID: rs114891564) as "With Likely benign allele", in ClinVar (classified 3x as likely benign by GeneDx, Ambry Genetics and one other submitter, 3x benign by Invitae and two other submitters). It was also identified in control databases in 122 of 272712 chromosomes at a frequency of 0.0004 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: African in 116 of 23992 chromosomes (freq: 0.005), Latino in 2 of 33848 chromosomes (freq: 0.00006), European in 2 of 124612 chromosomes (freq: 0.00002), and South Asian in 2 of 29800 chromosomes (freq: 0.00007), while the variant was not observed in the Other, Ashkenazi Jewish, East Asian or Finnish populations. The p.Phe1708= 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. In addition, 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. -
