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]

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Variant summary: The POLE c.5334C>T (p.Ala1778Ala) variant involves the alteration of a non-conserved nucleotide causing a synonymous change and 5/5 splice prediction tools predict no significant impact on normal splicing. ESE finder predicts that this variant may alter ESE binding. However, these predictions have yet to be confirmed by functional studies. This variant was found in 760/120604 control chromosomes (23 homozygotes), predominantly in the East Asian cohort at a frequency of 0.079643 (687/8626). This frequency is about 5607 times the estimated maximal expected allele frequency of a pathogenic POLE variant (0.0000142), suggesting this is likely a benign polymorphism found primarily in population(s) of East Asian origin. In addition, multiple clinical diagnostic laboratories classified this variant as benign. Taken together, this variant is classified as benign. -

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

This alteration is classified as 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.Ala1778= variant was identified in the literature however the frequency of this variant in an affected population was not provided (Yamaguchi_2016_27217144). The variant was also identified in dbSNP (ID: rs11146986) as “With Benign allele”, ClinVar and Clinvitae (5x as benign by GeneDx, Invitae, Quest Diagnostics, Ambry Genetics, Laboratory Corrporation of America), databases. The variant was not identified in Cosmic and MutDB databases. The variant was identified in control databases in 1594 of 276784 chromosomes (51 homozygous) at a frequency of 0.006 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database Feb 27, 2017). Breakdown of the observations by population include African in 6 of 24018 chromosomes (freq: 0.00025), “Other” in 13 of 6462 chromosomes (freq: 0.002), Latino in 3 of 34420 chromosomes (freq: 0.000087), European Non-Finnish in 14 of 126618 chromosomes (freq: 0.00011), East Asian in 1453 of 18856 chromosomes (freq: 0.08), and South Asian in 105 of 30778 chromosomes (freq: 0.003412), while the variant was not observed in the Ashkenazi Jewish and European Finnish populations. The p.Ala1778Ala 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, HumanSpliceFinder) do not predict a difference in splicing. In summary, based on the above information this variant meets our laboratory's criteria to be classified as benign. -
