Additional Information

The most common pathogenic mutations occur on the gene encoding for FMS-like tyrosine kinase 3 (FLT3). Length mutations in this gene through internal tandem duplications (ITD) in the juxtamembrane domain occur in about 25% of patients and lead to ligand-independent autophosphorylation and downstream signaling
