Objective(s): Mutant forms FMS-like tyrosine kinase-3 (FLT3), are reported in 25% of childhood acute lymphoid leukemia (ALL) and 30% of acute myeloid leukemia (AML) patients. In this study, drug response, growth promoting, and protein trafficking of FLT3 wild-type was compared with two active mutants (Internal Tandem Duplication (ITD)) and D835Y. Materials and Methods:FLT3 was expressed on fact...

Fms-like tyrosine kinase 3 (FLT3) is one of the most frequently mutated genes in acute myelogenous leukemia (AML) and mutation associated with poor prognosis patients. Two distinct types activating mutations have been identified AML samples. One internal tandem duplications juxtamembrane domain (FLT3-ITD) other point (FLT3-TKD). Gilteritinib a FLT3 inhibitor that inhibits both FLT3-ITD FLT3-TKD...

introduction: the secondary genetic changes other than the pml-rara fusion gene may contribute to the acute promyelocytic leukemogenesis. chromosomal alterations and mutation of flt3 tyrosine kinase receptor are the frequent genetic alterations in acute myeloid leukemia (aml). however, the prognostic significance of flt3 mutations in acute promyelocytic leukemia (apl) is not firmly established....

Background & Objective: FLT3-ITD mutation detection has been an integral part of diagnostic work ups focused on acute myeloid leukemia. However, some studies have indicated that the mutation is unstable during the various stages of the disease. The purpose of this study was to evaluate the stability of this marker in paired diagnosis-relapse samples using Delta-PCR method. Materials & Methods:...

Background: The secondary genetic changes other than the promyelocytic leukemia-retinoic acid receptor (PML-RARA) fusion gene may contribute to the acute promyelocytic leukemogenesis. Chromosomal alterations and mutation of FLT3 (FMS-like tyrosine kinase 3) tyrosine kinase receptor are the frequent genetic alterations in acute myeloid leukemia. However, the prognostic significance of FLT3 mutat...

FLT3 mutation is found in about 30% of acute myeloid leukemia (AML) patients and is associated with a poor prognosis. Several FLT3 inhibitors are undergoing investigation, while their clinical efficacies were lower than expected and several resistant mechanisms to FLT3 inhibitors have been demonstrated. Although most AML cells harboring FLT3 mutation co-express wild-type (Wt)-FLT3, it is not fu...

Objetivo: describir la frecuencia de las mutaciones FLT3-ITD y FLT3 TKD (D835) en 506 pacientes colombianos adultos con leucemia mieloide aguda (LMA) novo entre febrero 2019-junio 2022. Materiales Métodos: Se incluyeron muestras LMA 2019 junio realizó extracción ADN amplificación por PCR simultáneamente para región ITD el dominio tirosina quinasa del gen FLT3. Posteriormente, se hace digestión ...
