Colorectal cancer, susceptibility to, 12 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Oct 18, 2022 | This variant, c.3858_3881del, results in the deletion of 8 amino acid(s) of the POLE protein (p.Ala1288_Leu1295del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs759449495, gnomAD 0.0009%). This variant has not been reported in the literature in individuals affected with POLE-related conditions. ClinVar contains an entry for this variant (Variation ID: 422681). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. - |

Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Jun 30, 2023 | In-frame deletion of 8 amino acids in a non-repeat region; In silico analysis supports a deleterious effect on protein structure/function; Not observed at significant frequency in large population cohorts (gnomAD); Has not been previously published as pathogenic or benign to our knowledge; This variant is associated with the following publications: (PMID: 37250013) - |
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 20, 2018 | The c.3858_3881del24 variant (also known as p.A1288_L1295del) is located in coding exon 31 of the POLE gene. This variant results from an in-frame deletion of 24 nucleotides at positions 1288 to 1295. This results in the deletion of 8 amino acids between codons 3858 and 3881. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
