Subtypes

FLT3-ITD Mutated AML
AML with internal tandem duplications in the juxtamembrane domain of FLT3. ITD mutations cause ligand-independent receptor dimerization and constitutive activation. Associated with leukocytosis, high blast percentage, and poor prognosis, particularly when the ITD allelic ratio is high. Represents the most clinically significant FLT3 mutation subtype.
FLT3-TKD Mutated AML
AML with point mutations in the tyrosine kinase domain of FLT3, most commonly at codon D835. TKD mutations cause constitutive kinase activation but have a less adverse prognostic impact than ITD mutations. May co-occur with other mutations including NPM1.

Pathophysiology

5
FLT3 Receptor Constitutive Activation
FLT3 is a class III receptor tyrosine kinase normally involved in hematopoietic progenitor cell survival and proliferation. FLT3-ITD mutations cause ligand-independent receptor dimerization and constitutive autophosphorylation. FLT3-TKD mutations stabilize the active kinase conformation. Both result in aberrant downstream signaling.

This abstract describes FLT3-ITD/TKD mutations driving constitutive activation in AML, matching the mechanism described.
STAT5 Hyperactivation
FLT3-ITD mutations preferentially activate STAT5 signaling compared to wild-type FLT3 or TKD mutations. Phosphorylated STAT5 translocates to the nucleus and activates transcription of anti-apoptotic genes (BCL-XL, PIM1) and cell cycle regulators, promoting leukemic cell survival and proliferation.

RAS-MAPK Pathway Activation
FLT3 signaling activates the RAS-RAF-MEK-ERK cascade, driving cell proliferation and survival. This pathway is critical for the proliferative advantage of FLT3-mutated leukemic cells.
cell population proliferation link ↑ INCREASED
Apoptosis Resistance
FLT3-ITD-mediated STAT5 activation upregulates anti-apoptotic proteins including BCL-XL, MCL-1, and PIM kinases. This confers resistance to apoptosis and contributes to the aggressive clinical behavior of FLT3-ITD AML.

description: >-
  FLT3-mutated acute myeloid leukemia (AML) is characterized by activating mutations
  in the FMS-like tyrosine kinase 3 (FLT3) receptor, occurring in approximately 30%
  of newly diagnosed AML cases. The two main mutation types are internal tandem
  duplications (ITD) in the juxtamembrane domain (25%) and tyrosine kinase domain
  (TKD) point mutations (7-10%). FLT3-ITD mutations confer an adverse prognosis with
  high relapse rates, while FLT3-TKD mutations have intermediate prognostic impact.
  The development of FLT3 inhibitors (midostaurin, gilteritinib) has significantly
  improved outcomes for these patients, representing a key example of precision
  medicine in AML.

1. Disease Information
Edison Scientific Literature 45 citations 2026-04-05T15:24:48.895358

1. Disease Information

1.1 Concise overview

Acute myeloid leukemia (AML) is an aggressive hematologic malignancy characterized by the accumulation of immature hematopoietic precursors (blasts) in the bone marrow and peripheral blood. (negotei2023areviewof pages 1-3)

FLT3-mutated AML refers to AML harboring activating mutations in FLT3 (FMS-related receptor tyrosine kinase 3); these mutations occur in ~30% of newly diagnosed AML patients. (fedorov2023targetingflt3mutation pages 1-2)

Key concept—driver alteration: Activating FLT3 mutations are typically somatic lesions that confer proliferative/survival advantages to leukemic clones through constitutive signaling. (fedorov2023targetingflt3mutation pages 1-2)

1.2 Synonyms and alternative names

Commonly used in clinical and research contexts: - “FLT3-mutated AML” / “FLT3+ AML” (short2023treatmentofolder pages 1-2) - “FLT3-ITD AML” (internal tandem duplication) (fedorov2023targetingflt3mutation pages 1-2) - “FLT3-TKD AML” (tyrosine kinase domain point mutation) (fedorov2023targetingflt3mutation pages 1-2)

1.3 Key identifiers (availability in retrieved evidence)

  • ICD-9/ICD-10 codes (AML overall) were used in Global Burden of Disease (GBD) methods; these are not subtype-specific codes and are used for AML broadly. (zhou2024globalregionaland pages 2-4)
  • ELN (European LeukemiaNet) 2022 risk classification provides risk-grouping rules relevant to FLT3-ITD (no longer using allelic ratio). (lachowiez2023comparisonandvalidation pages 1-2, fedorov2023targetingflt3mutation pages 1-2)
  • MeSH / Orphanet / OMIM / subtype-specific MONDO identifiers for “FLT3-mutated AML” were not retrieved as explicit identifiers in the accessible text evidence.

1.4 Evidence source type

Most information below is derived from aggregated, disease-level resources (reviews, guidelines, and large registry/GBD studies) and from primary clinical trials (RATIFY, ADMIRAL, QuANTUM-First). (stone2017midostaurinpluschemotherapy pages 1-2, perl2019gilteritiniborchemotherapy pages 1-2, chen2024globalnationaland pages 1-2)


2. Etiology

2.1 Disease causal factors (mechanistic)

FLT3-mutated AML is driven by activating mutations in FLT3 leading to constitutive receptor signaling (PI3K, STAT5, RAS pathways), increasing leukemic cell survival and proliferation. (fedorov2023targetingflt3mutation pages 1-2)

2.2 Risk factors (AML overall; population-level)

Recent GBD-based analyses identify major modifiable risk factors associated with AML burden and mortality, including: - Smoking - High body mass index (BMI) - Occupational exposure to benzene and formaldehyde (chen2024globalnationaland pages 1-2, zhou2024globalregionaland pages 13-16)

GBD 2021 global statistics show incident AML cases increased from 79,372 (1990) to 144,645 (2021), while age-standardized incidence rate (ASIR) changed slightly (1.77 to 1.73 per 100,000). (zhou2024globalregionaland pages 2-4)

In older adults (60–89 years), 2019 estimates report 61,559 incident cases, 53,620 deaths, and 990,656 DALYs, and identify smoking, high BMI, and occupational benzene/formaldehyde as significant risk factors for mortality in 2019. (chen2024globalnationaland pages 1-2)

2.3 Protective factors

No specific genetic or environmental protective factors for FLT3-mutated AML were identified in the retrieved evidence.

2.4 Gene–environment interactions

No explicit gene–environment interaction evidence specific to FLT3-mutated AML was retrieved.


3. Phenotypes

3.1 Core clinical and laboratory phenotype (FLT3-ITD emphasis)

Across multiple sources, FLT3-ITD AML is repeatedly associated with higher disease burden and adverse clinical presentation: - Higher leukocyte counts and increased blast percentage at presentation, and higher relapse likelihood. (jalte2023flt3mutationsin pages 3-4) - Higher disease burden and inferior overall and relapse-free survival. (fedorov2023targetingflt3mutation pages 1-2)

General AML symptom cluster (not FLT3-specific but relevant to marrow failure) includes infections, anemia, and bleeding due to impaired normal hematopoiesis. (chen2024globalnationaland pages 1-2)

Frequency data gap: The retrieved sources did not provide robust population-level percentages for individual presenting symptoms (e.g., exact frequency of fever, bruising, etc.) specific to FLT3-mutated AML.

3.2 Suggested HPO terms (examples)

  • Leukocytosis — HP:0001974 (supported qualitatively for FLT3-ITD: higher leukocyte counts) (jalte2023flt3mutationsin pages 3-4)
  • Increased circulating blasts / blasts in blood — HP:0031846 (blast expansion implied) (jalte2023flt3mutationsin pages 3-4)
  • Bone marrow failure — HP:0005528 (mechanistic basis: disrupted hematopoiesis) (jalte2023flt3mutationsin pages 2-3, chen2024globalnationaland pages 1-2)
  • Anemia — HP:0001903 (AML symptom statement) (chen2024globalnationaland pages 1-2)
  • Thrombocytopenia — HP:0001873 (common severe AE; also typical AML cytopenia) (perl2019gilteritiniborchemotherapy pages 1-2)
  • Recurrent infections / infection susceptibility — HP:0002719 (AML symptom statement) (chen2024globalnationaland pages 1-2)
  • Bleeding — HP:0001892 (AML symptom statement) (chen2024globalnationaland pages 1-2)
  • Fever — HP:0001945 (common AML presentation; not quantified here)

4. Genetic / Molecular Information

4.1 Causal gene

  • FLT3 (fms related receptor tyrosine kinase 3). (fedorov2023targetingflt3mutation pages 1-2)

4.2 Pathogenic variant classes (somatic)

Two main mutation classes: - FLT3-ITD (internal tandem duplications in juxtamembrane domain): ~25% of newly diagnosed AML. (fedorov2023targetingflt3mutation pages 1-2) - FLT3-TKD (point mutations in the activation loop): ~7–10% of newly diagnosed AML. (fedorov2023targetingflt3mutation pages 1-2)

4.3 Co-mutations and modifying context

FLT3 mutations are enriched in AML with normal karyotype and are frequently co-mutated with NPM1 and/or DNMT3A. (short2023treatmentofolder pages 1-2)

4.4 Relapse genetics

FLT3 mutations may emerge at relapse; FLT3-ITD arises more commonly at relapse than TKD (8% vs 2%). (fedorov2023targetingflt3mutation pages 1-2)

In up to ~75% of patients with FLT3-ITD at diagnosis, the mutation persists at relapse, often with higher allelic burden. (fedorov2023targetingflt3mutation pages 1-2)

4.5 Resistance genetics (high clinical relevance)

Resistance to FLT3 inhibitors can be: - On-target FLT3 mutations, notably the gatekeeper FLT3 F691L (reported as conferring resistance to all current FLT3 inhibitors in one synthesis). (fedorov2023targetingflt3mutation pages 9-10) - Activation-loop FLT3 mutations (e.g., D835 variants) with class-specific resistance patterns (particularly relevant for type II inhibitors). (smith2022molecularprofileof pages 2-3) - Off-target RAS/MAPK pathway mutations (NRAS, KRAS, PTPN11, CBL, BRAF) emerging under selective pressure. (fedorov2023targetingflt3mutation pages 9-10)


5. Environmental Information

Environmental risk factors are better established for AML overall (not specifically FLT3-mutated AML): smoking, high BMI, and occupational exposures to benzene and formaldehyde contribute to AML-related burden and mortality in GBD analyses. (chen2024globalnationaland pages 1-2, zhou2024globalregionaland pages 13-16)


6. Mechanism / Pathophysiology

6.1 Causal chain (from mutation to phenotype)

1) FLT3 activating mutation (ITD/TKD) → 2) Constitutive FLT3 signaling via PI3K, STAT5, and RAS → 3) increased leukemic cell survival/proliferation and impaired differentiation → 4) accumulation of myeloblasts (bone marrow and blood) with suppression of normal hematopoiesis → 5) clinical manifestations (cytopenia-related infections/anemia/bleeding, leukocytosis/blast burden) and higher relapse risk. (fedorov2023targetingflt3mutation pages 1-2, jalte2023flt3mutationsin pages 3-4, chen2024globalnationaland pages 1-2)

6.2 Key downstream pathways and therapeutic implications

  • FLT3 signaling engages PI3K, STAT5, and RAS. (fedorov2023targetingflt3mutation pages 1-2)
  • STAT5-driven MCL-1 upregulation contributes to resistance to BCL-2 inhibition (venetoclax); FLT3 inhibitors can downregulate MCL-1, providing rationale for combination therapy. (fedorov2023targetingflt3mutation pages 2-4)

6.3 Bone marrow microenvironment mechanisms

A “protective environment within the bone marrow” makes eradication of FLT3-mutant cells difficult and contributes to resistance. (fedorov2023targetingflt3mutation pages 1-2)

Mechanistic studies highlight stromal/niche-derived signals (e.g., CXCL12, FGF2) as mediators of FLT3 inhibitor resistance via MAPK pathway reactivation and leukemia stem cell protection. (fedorov2023targetingflt3mutation pages 9-10, anderson2023microenvironmentalcxcl12deletion pages 10-12)

6.4 Suggested GO (biological process) terms (examples)

  • GO:0008283 cell population proliferation (consistent with proliferative signaling) (fedorov2023targetingflt3mutation pages 1-2)
  • GO:0006915 apoptotic process (inhibited; AML pathogenesis includes impaired apoptosis) (negotei2023areviewof pages 1-3)
  • GO:0030154 cell differentiation / myeloid cell differentiation (blocked in FLT3-ITD) (jalte2023flt3mutationsin pages 3-4)
  • GO:0007169 transmembrane receptor protein tyrosine kinase signaling pathway (FLT3 RTK) (fedorov2023targetingflt3mutation pages 1-2)
  • GO:0070371 ERK1 and ERK2 cascade (MAPK resistance axis) (fedorov2023targetingflt3mutation pages 9-10)

6.5 Suggested CL (cell type) terms (examples)

  • Hematopoietic stem cell — CL:0000037 (FLT3 expression context) (fedorov2023targetingflt3mutation pages 1-2)
  • Myeloid progenitor cell — CL:0000763 (progenitor compartment) (negotei2023areviewof pages 1-3)
  • Leukemia stem cell (concept used in microenvironment paper; map to hematopoietic stem/progenitor-like malignant cell; precise CL term may vary) (anderson2023microenvironmentalcxcl12deletion pages 10-12)

6.6 Recent developments (2023–2024 emphasis)

  • Resistance biology increasingly integrates microenvironmental protection and adaptive signaling (CXCL12/p38 axis; MAPK reactivation) and suggests combination strategies to suppress adaptive resistance. (anderson2023microenvironmentalcxcl12deletion pages 10-12, fedorov2023targetingflt3mutation pages 9-10)
  • 2024 AML therapeutic landscape reviews emphasize multiple newly approved targeted agents including FLT3 inhibitors and expanding combination strategies. (kantarjian2024currentstatusand pages 2-3)

7. Anatomical Structures Affected

7.1 Primary anatomical sites

  • Bone marrow: primary site of blast accumulation and microenvironmental protection. (negotei2023areviewof pages 1-3, fedorov2023targetingflt3mutation pages 1-2)
  • Peripheral blood: circulating blasts; abnormal precursor accumulation in marrow and blood. (negotei2023areviewof pages 1-3)

7.2 Extramedullary disease

Extramedullary involvement can occur in AML, including FLT3-mutated subsets, but the retrieved evidence did not provide organ-specific frequencies (e.g., spleen/liver infiltration rates) for FLT3-mutated AML.

7.3 Suggested UBERON terms

  • Bone marrow — UBERON:0002371 (negotei2023areviewof pages 1-3)
  • Peripheral blood — UBERON:0000178 (negotei2023areviewof pages 1-3)

8. Temporal Development

8.1 Onset

AML is an acute leukemia, with incidence increasing with age; ~80% of new AML cases occur in individuals aged ≥60. (chen2024globalnationaland pages 1-2)

8.2 Progression and relapse patterns (FLT3-mutated)

FLT3-ITD AML is characterized by high relapse risk after remission and persistence/emergence of FLT3-ITD at relapse in many patients. (fedorov2023targetingflt3mutation pages 1-2)


9. Inheritance and Population

9.1 Inheritance

FLT3 mutations defining FLT3-mutated AML are generally somatic, not inherited in a Mendelian pattern in typical cases (no germline inheritance pattern was supported in the retrieved evidence set).

9.2 Population patterns

  • AML burden disproportionately affects older adults and males in GBD analyses. (zhou2024globalregionaland pages 1-2, zhou2024globalregionaland pages 10-13)

10. Diagnostics

10.1 Required molecular testing

FLT3 mutation screening at diagnosis is described as mandatory, and WHO is cited as strongly advising FLT3 mutation screening in AML. (negotei2023areviewof pages 1-3)

10.2 Risk stratification updates (ELN 2022)

ELN 2022 removed FLT3-ITD allelic ratio from risk assignment; FLT3-ITD positivity is classified as intermediate risk irrespective of allelic ratio or NPM1 co-mutation (in the absence of adverse cytogenetics/other markers). (lachowiez2023comparisonandvalidation pages 1-2, fedorov2023targetingflt3mutation pages 1-2)

10.3 Testing workflows and MRD

Modern cohorts and validations used integrated cytogenetic and NGS approaches (karyotype, CLIA NGS, WES, fusion testing), and MRD is emphasized as a dynamic marker complementing baseline genetics. (lachowiez2023comparisonandvalidation pages 1-2)

10.4 FDA-approved test requirement (implementation detail)

For gilteritinib in relapsed/refractory AML, the FDA approval specifies use in patients with a FLT3 mutation “as detected by an FDA-approved test.” (pulte2021fdaapprovalsummary pages 1-3)

10.5 Differential diagnosis

Differential diagnosis details (e.g., AML vs MDS/AML or mixed phenotype acute leukemia) were not systematically extractable from the retrieved evidence set for this report.


11. Outcome / Prognosis

11.1 Baseline prognosis of FLT3-ITD AML

Prior to widespread FLT3 inhibitor use, a meta-analysis cited in a 2023 review reported overall survival HR 1.86 and relapse-free survival HR 1.75 for FLT3-ITD (adverse prognosis). (fedorov2023targetingflt3mutation pages 1-2)

11.2 Prognosis modified by FLT3 inhibitors (key trial statistics)

  • Midostaurin (frontline with intensive chemotherapy): RATIFY showed OS and EFS benefit (hazard ratio for death 0.78; one-sided P=0.009; hazard ratio for event/death 0.78; one-sided P=0.002). (stone2017midostaurinpluschemotherapy pages 1-2)
  • Gilteritinib (relapsed/refractory): ADMIRAL showed median OS 9.3 vs 5.6 months (HR 0.64). (perl2019gilteritiniborchemotherapy pages 1-2)
  • Quizartinib (newly diagnosed FLT3-ITD): QuANTUM-First is associated with improved OS and MRD clearance correlating with OS in post hoc analyses. (levis2022quantumfirsttrialflt3itdspecific pages 1-1)

12. Treatment

12.1 Current standard and approved therapies (key agents)

Evidence from recent reviews and pivotal trials supports: - Midostaurin + intensive chemotherapy (7+3-based induction and consolidation) for newly diagnosed FLT3-mutated AML. (fedorov2023targetingflt3mutation pages 1-2) - Gilteritinib monotherapy for relapsed/refractory FLT3-mutated AML. (fedorov2023targetingflt3mutation pages 1-2) - Quizartinib + chemotherapy for newly diagnosed FLT3-ITD AML (regulatory status discussed in 2024 reviews). (cortes2024quizartinibapotent pages 1-2, leifheit2024enhancingtherapeuticefficacy pages 6-7)

Table: This table summarizes the principal FLT3-targeted therapies used in FLT3-mutated AML, their pivotal trial evidence, and regulatory context. It is useful for quickly comparing frontline versus relapsed/refractory use, efficacy benchmarks, and approval timing.

12.2 Safety and monitoring (real-world implementation)

Gilteritinib labeling includes boxed warning for differentiation syndrome, and warnings for QT prolongation, PRES, pancreatitis, and embryo-fetal toxicity, requiring frequent ECG and chemistry monitoring. (pulte2021fdaapprovalsummary pages 1-3)

12.3 Combination strategies (active development)

Because FLT3-ITD can mediate venetoclax resistance and relapse, combination strategies incorporating FLT3 inhibitors with venetoclax and/or hypomethylating agents are under investigation and show encouraging early results in reviews; mechanistically, FLT3 inhibition can reduce STAT5→MCL-1 signaling that contributes to venetoclax resistance. (short2023treatmentofolder pages 1-2, fedorov2023targetingflt3mutation pages 2-4)

12.4 Allogeneic hematopoietic stem cell transplantation (allo-HSCT)

Given poor relapsed/refractory outcomes and high relapse risk in FLT3-ITD AML, allo-HSCT is generally recommended in first complete remission in many treatment paradigms. (fedorov2023targetingflt3mutation pages 1-2)

12.5 Suggested MAXO terms (examples)

  • Antineoplastic chemotherapy regimen — MAXO:0000647 (intensive induction/consolidation)
  • Tyrosine kinase inhibitor therapy — MAXO:0000644 (FLT3 inhibitors)
  • Allogeneic hematopoietic stem cell transplantation — MAXO:0000747
  • Measurable residual disease monitoring — (MAXO term availability may vary; concept supported in ELN-related sources) (lachowiez2023comparisonandvalidation pages 1-2)

13. Prevention

No primary prevention specific to FLT3-mutated AML was identified; prevention strategies for AML overall focus on modifying population-level risk factors highlighted in GBD analyses: - Tobacco smoking reduction - Obesity/high BMI reduction - Occupational exposure control for benzene and formaldehyde (chen2024globalnationaland pages 1-2, zhou2024globalregionaland pages 13-16)


14. Other Species / Natural Disease

This section is not directly applicable as a “naturally occurring” transmissible disease; however, AML-like phenotypes driven by FLT3-ITD are modeled in animals (see Model Organisms).


15. Model Organisms

15.1 Common model systems used in FLT3-ITD AML research

  • Genetically engineered mouse models (GEMMs) focusing on bone marrow niche resistance and leukemia stem cell biology in Flt3-ITD AML. (anderson2023microenvironmentalcxcl12deletion pages 10-12)
  • In vivo xenografts and PDX models using FLT3-ITD AML cells to study adaptive resistance and to test inhibitor combinations. (azhar2023rationalpolypharmacologicaltargeting pages 2-3, xiao2023gnf7anovel pages 1-2)
  • Engineered Ba/F3 cells expressing FLT3-ITD and drug-resistant variants for kinase-inhibitor testing and resistance mapping. (azhar2023rationalpolypharmacologicaltargeting pages 2-3)
