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]

Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Oct 22, 2022	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 c.1534G>A variant is predicted to result in the amino acid substitution p.Ala512Thr. This variant has been reported in an individual with breast cancer (Table S3, Guindalini et al. 2022. PubMed ID: 35264596), however it is not known if this variant co-occurred with any known pathogenic variant in other breast cancer-related genes. This variant is reported in 0.14% of alleles in individuals of African descent in gnomAD, which may be too frequent to be an undocumented pathogenic variant. This variant has been interpreted as both uncertain and likely benign in the ClinVar database (https://www.ncbi.nlm.nih.gov/clinvar/variation/405691). Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
