Variant summary
Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PVS1PM2PP5
The NM_006231.4(POLE):c.4480C>T(p.Gln1494Ter) variant causes a stop gained change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. Q1494Q) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Submissions by phenotype
not provided Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Oct 09, 2023 | This sequence change creates a premature translational stop signal (p.Gln1494*) in the POLE gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in POLE are known to be pathogenic (PMID: 23230001, 25948378, 30503519). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with thyroid cancer and breast cancer (PMID: 32792570). ClinVar contains an entry for this variant (Variation ID: 1740913). For these reasons, this variant has been classified as Pathogenic. - |
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Feb 17, 2020 | The p.Q1494* variant (also known as c.4480C>T), located in coding exon 35 of the POLE gene, results from a C to T substitution at nucleotide position 4480. This changes the amino acid from a glutamine to a stop codon within coding exon 35. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. However, loss of function of POLE has not been clearly established as a mechanism of disease. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
