Tandem duplication mutation
WebDec 6, 2014 · Background Partial tandem duplication mutations of the Mixed Lineage Leukemia gene ( MLL -PTD) can be found in about 10% of patients with AML, especially in patients with normal karyotype AML. The mutation generates a self-fusion within the N-terminal part of MLL and has been shown to be leukemogenic in mouse models.

WebThese structural variants include deletions, tandem duplications, inversions, mobile element insertions. The mutation rate is also much higher than microscopic structural variants, estimated by two studies at 16% and 20% respectively, both of which are probably underestimates due to the challenges of accurately detecting structural variants.

WebOct 19, 2024 · There are two common types of mutations, the internal tandem duplication (ITD) and the tyrosine kinase domain (TKD) mutations. The FLT3 ITD mutation is seen in about 25% to 35% of adult AMLs. 4-6 FLT3 ITDs typically involve the juxtamembrane domain at exons 11 and 12 of FLT3.
