Nucleophosmin-1 (NPM1) mutations represent the most frequent gene alteration in acute myeloid leukemia (AML). The most common NPM1 mutation type, accounting for 75 to 80% of cases, is referred to as mutation A (NPM1-mutA). These NPM1 alterations have been shown to possess prognostic significance because they appear to identify patients who will benefit from(More)
FLT3 internal tandem duplication (ITD) mutations are frequently detected at diagnosis in cytogenetically normal acute myeloid leukaemia (CN-AML) and predict unfavourable outcome. FLT3 ITD is an unstable aberration and may be lost or acquired at relapse. Recent whole genome sequencing studies have suggested that FLT3 ITD(+)ve AML relapse may evolve from(More)
MicroRNAs (miRNAs), small non-coding RNAs that regulate gene expression post-transcriptionally, are involved in many complex cellular processes. Several miRNAs are differentially expressed in hematopoietic tissues and play important roles in normal differentiation, but, when aberrantly regulated, contribute to the abnormal proliferation and differentiation(More)
Mutations in the Nucleophosmin (NPM1) gene have been recently described to occur in about one-third of acute myeloid leukemias (AML) and represent the most frequent genetic alteration currently known in this subset. These mutations generate an elongated NPM1 protein that localizes aberrantly in the cytoplasm. In analogy with Flt3 alterations, NPM1 mutations(More)
A total of 143 adult acute myeloid leukemia (AML) patients with available karyotype (K) and FLT3 gene mutational status were assessed for minimal residual disease (MRD) by flow cytometry. Twenty-two (16%) patients had favorable, 115 (80%) intermediate, and 6 (4%) poor risk K; 19 of 129 (15%) carried FLT3-ITD mutation. Considering postconsolidation MRD(More)
The treatment of multiple acyl-CoA-dehydrogenase deficiency (MADD) includes a low-fat, low-protein, high-carbohydrate diet, avoiding long fasting periods. However, there is no useful biochemical marker to determine the response to different diets or fasting periods. The aims of this study are to report a patient with MADD, diagnosed through a newborn(More)
MicroRNAs (miRNAs) are small non-coding RNAs involved in the regulation of critical cell processes such as apoptosis, cell proliferation and differentiation. A small set of miRNAs is differentially expressed in hematopoietic cells and seemingly has an important role in granulopoiesis and lineage differentiation. In this study, we analysed, using a(More)
The translocation t(16;21) involving RUNX1 (AML1) and resulting in the RUNX1-CBFA2T3 fusion is a rare but recurrent abnormality mostly found in therapy-related acute myeloid leukemia (t-AML) associated with agents targeting topoisomerase II (topo II). We characterized, at the genomic level, the t(16;21) translocation in a patient who developed t-AML after(More)
Since the publication of this article, the authors have identified an error within Table 2, namely that the AML subgroups listed at the bottom of the table were incorrect. The correct table is shown here. The article has also been rectified, and now carries the correct information. The Publishers apologize for any inconvenience this has caused. a TCGA b(More)
OBJECTIVES Mutations in the C-terminal region of the nucleophosmin (NPM1) gene occur in approximately 60% of acute myeloid leukemia (AML) cases with normal karyotype and represent the most common genetic lesion presently known in this disease. Because of their frequency and favorable impact on prognostic outcome, screening for this aberration is currently(More)
