Purpose: FMS-like tyrosine kinase-3 (FLT3) internal tandem duplication (FLT3-ITD) mutations are common in patients with acute myeloid leukemia (AML). These patients regularly develop resistance to FLT3 inhibitors suggesting that targeted combination drug strategies are needed to enhance AML therapy
The same FLT3-internal tandem duplication (ITD) positive clone was detected at diagnosis and relapse, but not at birth, in a child with M1 acute myeloid leukemia. Single nucleotide polymorphism arrays demonstrated that chromosome 13 acquired uniparental disomy, in association with del(9q), represented a progressive event in the course of the disease, and it was responsible for the homozygous FL...
BACKGROUND Several genetic aberrations with prognostic impact in first-line therapy have been described in patients with acute myeloid leukemia and normal karyotype. However, little is known about the influence of these aberrations on outcome after relapse. This study aimed to identify clinical and molecular risk factors for patients with relapsed acute myeloid leukemia with normal karyotype. ...
Somatic mutations in the mitochondrial DNA (mtDNA) displacement loop (D-loop) region have been frequently detected in various human cancers. In a previous study, we identified a polyplasmic 260-bp tandem duplication and triplication mutation in the mtDNA D-loop of one gastric cancer. In the present study, we adopted a more sensitive back-to-back polymerase chain reaction method to screen for th...
Tandem gene duplication is an important mutational process in evolutionary adaptation and human disease. Hypothetically, two tandem gene copies should produce twice the output of a single gene, but this expectation has not been rigorously investigated. Here, we show that tandem duplication often results in more than double the gene activity. A naturally occurring tandem duplication of the Alcoh...
