WebWe have screened 69 AML-derived cell lines for FLT3 mutations. Four of these cell lines showed ITD of the FLT3 gene, none carried a D835 point mutation. Two cell lines (MUTZ-11 and MV4-11) expressed exclusively the mutated allele, the other two cell lines (MOLM-13 and PL-21) displayed a mutated and the wild-type version of the gene. WebJan 24, 2024 · There are two canonical types of FLT3 mutations: internal tandem duplication within the juxta-membrane domain ( FLT3 -ITD) found in 25–30% of AML patients and point mutations in the tyrosine kinase domain ( FLT3 -TKD) in 5–7% of cases [ 1, 2 ].
