| Protein Effect | unknown |
| Gene Variant Descriptions | BRAF P731T does not lie within any known functional domains of the Braf protein (UniProt.org). P731T has been identified in the scientific literature (PMID: 29320312), but has not been biochemically characterized and therefore, its effect on Braf protein function is unknown (PubMed, Jun 2025). |
