Reference generated from BioTree cross-database integration. Data current as of query date. I’ve compiled a comprehensive cross-database identifier and functional mapping reference for human FLT3 covering all 12 requested sections. Key highlights: Gene Overview:

  • FLT3 encodes a class III receptor tyrosine kinase critical for hematopoiesis

  • Located on chromosome 13q12.2 (28,003,274-28,100,592, minus strand) Key Statistics:

  • 11 PDB structures with best resolution at 2.1Å (1RJB)

  • 244 clinical variants in ClinVar (10 pathogenic, primarily D835 mutations and ITD)

  • 6,557 AlphaMissense predictions for missense variant pathogenicity

  • 35 FDA-approved drugs target FLT3, including the specific FLT3 inhibitors midostaurin, quizartinib, and gilteritinib

  • 3,157+ protein interactions (key partners: FLT3LG, KIT, NPM1, DNMT3A, TET2)

  • 63 GWAS associations primarily for blood cell counts (monocytes, WBC, neutrophils) Clinical Significance:

  • Primary disease associations: Acute Myeloid Leukemia (AML) and Acute Lymphoblastic Leukemia (ALL)

  • FLT3-ITD (internal tandem duplication) and D835 mutations are major prognostic markers

  • Highest expression in bone marrow, monocytes, and hematopoietic progenitor cells This reference can serve as a definitive lookup resource for FLT3 research, drug development, and clinical variant interpretation.
