| Impact List | missense |
| Protein Effect | unknown |
| Gene Variant Descriptions | BRAF N581Y lies within the protein kinase domain of the Braf protein (UniProt.org). N581Y results in increased cell viability in culture (PMID: 32540409), but has not been fully biochemically characterized and therefore, its effect on Braf protein function is unknown. |
