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]

Polymerase proofreading-related adenomatous polyposis Benign:1
Likely benign, no assertion criteria providedclinical testingDepartment of Pathology and Laboratory Medicine, Sinai Health System-The POLE p.Gly1527= variant was not identified in the literature nor was it identified in the Cosmic and MutDB. The variant was identified in dbSNP (ID: rs772646117) “With Likely benign allele”, ClinVar (classified as likely benign by GeneDx and Invitae), Clinvitae (2x), and in control databases in 5 of 256250 chromosomes at a frequency of 0.00002 (Genome Aggregation Database Feb 27, 2017). Breakdown of the observations by population include Latino in 2 of 28422 chromosomes (freq: 0.00007) and East Asian in 3 of 17724 chromosomes (freq: 0.0002), while not observed in the African, Other, European Non-Finnish, Ashkenazi Jewish, European Finnish, and South Asian populations. The p.Gly1527= 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 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. -
Hereditary cancer-predisposing syndrome Benign:1
Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsJun 18, 2018This 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. -
