CSF3R | N579Y | missense | gain of function | CSF3R N579Y lies within fibronectin type-III domain 5 of the Csf3r protein (UniProt.org). N579Y confers a gain of function to Csf3r as demonstrated by cytokine-independent growth and increased Erk1/2 and Stat3 phosphorylation in cultured cells (PMID: 36579444). | |
CSF3R | Q739* | nonsense | unknown | CSF3R Q739* results in a premature truncation of the Csf3r protein at amino acid 739 of 836 (UniProt.org). Q739* has been identified in the scientific literature (PMID: 25865944, PMID: 29932212, PMID: 36579444), but has not been biochemically characterized and therefore, its effect on Csf3r protein function is unknown (PubMed, Aug 2024). |

CSF3R T618I | hematologic cancer | sensitive | Ruxolitinib | Preclinical - Cell culture | Actionable | In a preclinical study, Jakafi (ruxolitinib) inhibited growth of a transformed cell line expressing CSF3R T618I in culture (PMID: 36579444). | 36579444 |
CSF3R N579Y CSF3R Q739* CSF3R Q741* | chronic neutrophilic leukemia | predicted - sensitive | Ruxolitinib | Preclinical - Patient cell culture | Actionable | In a preclinical study, Jakafi (ruxolitinib) treatment inhibited colony formation of hematopoietic progenitor cells isolated from the bone marrow of a patient with chronic neutrophilic leukemia harboring CSF3R N579Y, Q739*, and Q741* in culture (PMID: 36579444). | 36579444 |
CSF3R N579Y | hematologic cancer | sensitive | Ruxolitinib | Preclinical - Cell culture | Actionable | In a preclinical study, Jakafi (ruxolitinib) treatment inhibited colony formation and decreased viability of transformed cells expressing CSF3R N579Y in culture (PMID: 36579444). | 36579444 |
