Fatos de ação
| Biomarcador | BIO-FLT3-D835 |
|---|---|
| Variante | Mutação de resistência do guardião de gatekeeper F691L (post-FLT3i) |
| Doença | DIS-AML |
| Nível ESCAT | IIA |
| Combinações recomendadas | salvage chemo + allo-SCT (preferred when fit), clinical trial (next-gen FLT3i, crenolanib, FF-10101), venetoclax + azacitidine (off-label salvage) |
| Contraindicated monotherapy | gilteritinib (resistência cruzada F691L), quizartinib(resistência transversal F691) |
| Resumo das provas | FLT3-F691L is a gatekeeper mutation arising under FLT3-TKI selective pressure (gilteritinib, quizartinib). Confers cross-resistance to most current FLT3i. Crenolanib (investigational type-I) and next-gen FLT3i retain partial activity. No approved targeted option — clinical trial enrollment or salvage chemo + allo-SCT. |
Notas
ESCAT IIA (resistance biomarker — guides what NOT to use). OncoKB Level R1. Cell intentionally uses BIO-FLT3-D835 as biomarker_id because F691L is a TKD/kinase-domain mutation captured under the FLT3-D835 / TKD entity per the cherry-picked BIO file (no separate F691L biomarker). variant_qualifier disambiguates. Clinical use: trigger ctDNA / BM rebiopsy at gilteritinib failure to detect F691L vs D835 emergence.
