fms-like tyrosine kinase-3 mutation in a child with standard-risk all and normal karyotype
نویسندگان
چکیده
fms-like tyrosine kinase-3 is a receptor tyrosine kinase expressed by immature hematopoietic cells and is important for the normal development of stem cells and the immune system. mutations of fms-like tyrosine kinase-3 have been detected in about 30% of patients with acute myelogenous leukemia and a small number of patients with acute lymphoblastic leukemia. the fms-like tyrosine kinase-3 mutations most often involve small tandem duplications of amino acids within the juxtamembrane domain of the receptor and are called internal tandem duplications. the other type of mutations in fms-like tyrosine kinase-3 is located in the activation loop of the second tyrosine kinase domain. multiple studies have shown that activating mutations of fms-like tyrosine kinase-3 are common in blasts from patients with aml but are rarely found in adult patients with acute lymphoblastic leukemia. in addition, activating flt3 mutations occur only rarely in t-all cases. here we report a 3-year-old girl with all who had a mutation in fms-like tyrosine kinase-3 / internal tandem duplications. keywords: fms-like tyrosine kinase-3, mutation, acute lymphoblastic leukemia, childhood.

متن کاملCytogenetic and FMS-Like Tyrosine Kinase 3 Mutation Analyses in Acute Promyelocytic Leukemia Patients
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...
