| Protein Effect | loss of function |
| Gene Variant Descriptions | POLE F367S lies within the exonuclease domain of the Pole protein (PMID: 29352080). F367S results in reduced exonuclease activity and increased replication error rates compared to wild-type Pole in in vitro assays (PMID: 29352080, PMID: 25228659). |

| POLE F367S | colorectal cancer | predicted - sensitive | Pembrolizumab | Case Reports/Case Series | Actionable | In a retrospective study, treatment with immune checkpoint inhibitors resulted in an overall response rate of 89% (22/29) and a disease control rate of 92% in metastatic colorectal cancer patients harboring pathogenic POLE/POLD1 variants, including a complete response in a patient harboring POLE F367S treated with Keytruda (pembrolizumab) (PMID: 38777726). | 38777726 |
