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]

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Oct 15, 2019 | This sequence change creates a premature translational stop signal (p.Tyr1078Profs*42) in the POLE gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with POLE-related disease. Missense variants that disrupt the 3'-5' exonuclease (proof-reading) activity of the POLE protein, while not abolishing its polymerase enzyme activity, are associated with an increased risk for colonic adenomatous polyps and colon cancer (PMID: 23263490, 23447401). Loss-of-function truncating variants, which result in an absent or severely disrupted POLE protein, are therefore unlikely to be associated with disease. Without further clinical and genetic evidence, however, this variant has been classified as a Variant of Uncertain Significance. - |
