It is expected to result in an absent or disrupted protein product. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the ExAC database. 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.
