Functional Summary
Error in OpenAI Consolidation. OncoKB: POLES297PPOLES297PSomaticNCBI Gene:5426|Show additional gene information Variant OverviewPOLE, the catalytic subunit of DNA polymerase epsilon, is an enzyme involved in DNA replication and repair. Select POLE mutations lead to ultra-high mutation rates, most frequently in endometrial and colorectal cancer.The POLE S297P mutation has not specifically been reviewed by the OncoKB team. However, POLE S297F/Y are likely oncogenic, and therefore POLE S297P is considered likely oncogenic.Hide mutation effect description The POLE S297P mutation has not specifically been reviewed by the OncoKB team. However, we have mutation effect descriptions for POLE S297F/Y JAX-CKB: No results found
