Genes affected

FLT3 (HGNC:3765): (fms related receptor tyrosine kinase 3) This gene encodes a class III receptor tyrosine kinase that regulates hematopoiesis. This receptor is activated by binding of the fms-related tyrosine kinase 3 ligand to the extracellular domain, which induces homodimer formation in the plasma membrane leading to autophosphorylation of the receptor. The activated receptor kinase subsequently phosphorylates and activates multiple cytoplasmic effector molecules in pathways involved in apoptosis, proliferation, and differentiation of hematopoietic cells in bone marrow. Mutations that result in the constitutive activation of this receptor result in acute myeloid leukemia and acute lymphoblastic leukemia. [provided by RefSeq, Jan 2015]

The c.2716T>C (p.F906L) alteration is located in exon 22 (coding exon 22) of the FLT3 gene. This alteration results from a T to C substitution at nucleotide position 2716, causing the phenylalanine (F) at amino acid position 906 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
