Abstract
In myeloid neoplasms, both fusion genes and gene mutations are well-established events identifying clinicopathological entities. In this study, we present a thus far undescribed t(X;21)(p11.4;q22.12) in five cases with myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML). The translocation was isolated or accompanied by additional changes. It did not generate any fusion gene or gene deregulation by aberrant juxtaposition with regulatory sequences. Molecular analysis by targeted next-generation sequencing showed that the translocation was accompanied by at least one somatic mutation in TET2, EZH2, RUNX1, ASXL1, SRSF2, ZRSR2, DNMT3A, and NRAS genes. Co-occurrence of deletion of RUNX1 in 21q22 and of BCOR in Xp11 was associated with t(X;21). BCOR haploinsufficiency corresponded to a significant hypo-expression in t(X;21) cases, compared to normal controls and to normal karyotype AML. By contrast, RUNX1 expression was not altered, suggesting a compensatory effect by the remaining allele. Whole transcriptome analysis showed that overexpression of HOXA9 differentiated t(X;21) from both controls and t(8;21)-positive AML. In conclusion, we characterized a new recurrent reciprocal t(X;21)(p11.4;q22.12) chromosome translocation in MDS and AML, generating simultaneous BCOR and RUNX1 deletions rather than a fusion gene at the genomic level.

Abstract
Mantle cell lymphoma is a B-cell malignancy, which, in its classic form, usually involves lymph nodes and extranodal sites, and, among the extranodal sites, the gastrointestinal tract and the Waldeyer's ring are most prevalent. MCL is rarely reported in the ocular adnexa, a site more frequently affected by extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue, which is a form of low-grade malignancy. The diagnosis of MCL presenting in the ocular adnexa requires special attention as its rarity in this location combined with the not uncommon CD5 negativity of the disease when occurring in the ocular adnexa, may lead the pathologist to overlook the diagnosis and misinterpret MCL as marginal zone B cell lymphoma, which has a totally different behavior. Herein, we present a case of primary bilateral conjunctival CD5-negative MCL in a patient having no other sites affected by lymphoma and we discuss possible diagnostic pitfalls.

Abstract
High-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements (DH/TH-HGBL) still miss an in-depth genomic characterization. To identify accompanying genetic events, we performed a pilot study on 7 cases by applying DNA microarray and targeted NGS sequencing. Interestingly, the genetic background of DH/TH-HGBL is largely overlapping with that of other high-grade/poor prognosis lymphomas. Namely, copy number abnormalities were trisomy of chromosome 7 and chromosome 8q gain, encompassing MYC. Among gene variants, those affecting transcription factors (MYC, FOXO1), epigenetic modulators (KMT2D, EZH2 and CREEBP), and anti-apoptotic gene (BCL2), were recurrent. MYC and BCL2 were mutated in 3 and 5 cases, respectively. In addition, mutations of FOXO1, previously reported in Diffuse Large B-Cell Lymphomas, were also detected. Clarifying the genomic background of this subset of high-risk lymphomas will pave the way for the clinical use of new biomarkers to: (1) monitor treatment response and; (2) consider alternative targeted therapies.

Abstract
Platelet-derived growth factor receptor B (PDGFRB) gene rearrangements define a unique subgroup of myeloid and lymphoid neoplasms frequently associated with eosinophilia and characterized by high sensitivity to tyrosine kinase inhibition. To date, various PDGFRB/5q32 rearrangements, involving at least 40 fusion partners, have been reported. However, information on genomic and clinical features accompanying rearrangements of PDGFRB is still scarce. Here, we characterized a series of 14 cases with a myeloid neoplasm using cytogenetic, single nucleotide polymorphism array, and next-generation sequencing. We identified nine PDGFRB translocation partners, including the KAZN gene at 1p36.21 as a novel partner in a previously undescribed t(1;5)(p36;q33) chromosome change. In all cases, the PDGFRB recombination was the sole cytogenetic abnormality underlying the phenotype. Acquired somatic variants were mainly found in clinically aggressive diseases and involved epigenetic genes (TET2, DNMT3A, ASXL1), transcription factors (RUNX1 and CEBPA), and signaling modulators (HRAS). By using both cytogenetic and nested PCR monitoring to evaluate response to imatinib, we found that, in non-AML cases, a low dosage (100–200 mg) is sufficient to induce and maintain longstanding hematological, cytogenetic, and molecular remissions.

Abstract
Warsaw breakage syndrome (WABS), is caused by biallelic mutations of DDX11, a gene coding a DNA helicase. We have recently reported two affected sisters, compound heterozygous for a missense (p.Leu836Pro) and a frameshift (p.Lys303Glufs*22) variant. By investigating the pathogenic mechanism, we demonstrate the inability of the DDX11 p.Leu836Pro mutant to unwind forked DNA substrates, while retaining DNA binding activity. We observed the accumulation of patient-derived cells at the G2/M phase and increased chromosomal fragmentation after mitomycin C treatment. The phenotype partially overlaps with features of the Fanconi anemia cells, which shows not only genomic instability but also defective mitochondria. This prompted us to examine mitochondrial functionality in WABS cells and revealed an altered aerobic metabolism. This opens the door to the further elucidation of the molecular and cellular basis of an impaired mitochondrial phenotype and sheds light on this fundamental process in cell physiology and the pathogenesis of these diseases.

Abstract
Recurrent somatic mutations in ETNK1 (Ethanolamine-Kinase-1) were identified in several myeloid malignancies and are responsible for a reduced enzymatic activity. Here, we demonstrate in primary leukemic cells and in cell lines that mutated ETNK1 causes a significant increase in mitochondrial activity, ROS production, and Histone H2AX phosphorylation, ultimately driving the increased accumulation of new mutations. We also show that phosphoethanolamine, the metabolic product of ETNK1, negatively controls mitochondrial activity through a direct competition with succinate at mitochondrial complex II. Hence, reduced intracellular phosphoethanolamine causes mitochondria hyperactivation, ROS production, and DNA damage. Treatment with phosphoethanolamine is able to counteract complex II hyperactivation and to restore a normal phenotype.

Abstract
Fanconi Anemia (FA) is a disease characterized by bone marrow (BM) failure and aplastic anemia. In addition to a defective DNA repair system, other mechanisms are involved in its pathogenesis, such as defective mitochondrial metabolism, accumulation of lipids, and increment of oxidative stress production. To better understand the role of these metabolic alterations in the process of HSC maturation in FA, we evaluated several biochemical and cellular parameters on mononuclear cells isolated from the bone marrow of FA patients or healthy donors. To mimic the cellular residence in the BM niche or their exit from the BM niche to the bloodstream, cells have been grown in hypoxic or normoxic conditions, respectively. The data show that, in normoxic conditions, a switch from anaerobic to aerobic metabolism occurs both in healthy and in pathological samples. However, in FA cells this change is associated with altered oxidative phosphorylation, the increment of oxidative stress production, no activation of the endogenous antioxidant defenses and arrest in the G2M phase of the cell cycle. By contrast, FA cells grown in hypoxic conditions do not show cell cycle and metabolic alterations in comparison to the healthy control, maintaining both an anaerobic flux. The data reported herein suggests that the passage from the BM niche to the bloodstream represents a crucial point in the FA pathogenesis associated with mitochondrial dysfunction. MNCs isolated from the bloodstream of FA patients display a metabolic defect. The metabolic defect is not evident in FA-MNCs isolated from the bone marrow niche. The metabolic defect seems to be linked to the oxygen availability. The passage from the BM niche to the bloodstream is crucial in FA pathogenesis.

Abstract
The unbalanced translocation dic(1;7)(q10;p10) in myelodysplastic syndromes (MDS) is originated by centromeric juxtaposition resulting into 1q trisomy and 7q monosomy. More than half of cases arise after chemo/radio-therapy. To date, given the absence of genes within the centromeric regions, no specific molecular events have been identified in this cytogenetic subgroup. We performed the first comprehensive genetic and epigenetic analysis of MDS with dic(1;7)(q10;p10) compared to normal controls and therapy-related myeloid neoplasms (t-MNs). RNA-seq showed a unique downregulated signature in dic(1;7) cases, affecting more than 80% of differentially expressed genes. As revealed by pathway and gene ontology analyses, downregulation of ATP-binding cassette (ABC) transporters and lipid-related genes and upregulation of p53 signaling were the most relevant biological features of dic(1;7). Epigenetic supervised analysis revealed hypermethylation at intronic enhancers in the dicentric subgroup, in which low expression levels of enhancer putative target genes accounted for around 35% of the downregulated signature. Enrichment of Krüppel-like transcription factor binding sites emerged at enhancers. Furthermore, a specific hypermethylated pattern on 1q was found to underlie the hypo-expression of more than 50% of 1q-deregulated genes, despite trisomy. In summary, dic(1;7) in MDS establishes a specific transcriptional program driven by a unique epigenomic signature.

Abstract
BACKGROUND Italian External Quality Assessment (IEQA) Program in Cytogenetics, established in 2001 by the Istituto Superiore di Sanità (ISS), covers both Constitutional and Oncohaematological diagnosis. In 2013, performance criteria were defined and adopted. In this paper, we present the data from the first 4 years of activity (2013-2016) following the introduction of performance criteria. METHODS The enrollment is voluntary, fee-based and open to both public and private Italian laboratories. The scheme is annual and retrospective; a national panel of experts assess technical, analytical and interpretative performance. RESULTS Overall, 95 distinct Italian laboratories participated in different Cytogenetics IEQA schemes over the 2013-2016 years and most of the laboratories took part in Constitutional diagnosis. General hospitals and local health centers represented 40% of the total participants and the percentage of laboratories from Northern Regions was more than 45% of total participants throughout the 4-year period. As regards the performance evaluation, on average, 11, 9 and 23% of participants were marked as poor performers in Prenatal, Postnatal and Oncohaematological schemes, respectively. With regard to critical errors, ISCN nomenclature in Prenatal and Postnatal schemes, and interpretation in Oncohaematological diagnosis, were identified as main issues. On the other hand, karyotype errors and inadequate analysis decreased strongly, over the 4 years, in Constitutional and Oncohaematological diagnosis, respectively. CONCLUSIONS Our data show that the introduction of poor performance encourages laboratories to address critical issues, and the IEQA participation helps to improve quality in cytogenetic testing.

Abstract
Abstract
Atypical chronic myeloid leukemia (aCML) is a clonal disorder belonging to the myelodysplastic/myeloproliferative syndromes. About 13% of aCML cases carry somatic mutations in ETNK1 gene, encoding for H243Y, N244S, and G245V substitutions. We previously showed that ETNK1 mutations cause a decreased catalytic activity of the enzyme. Despite this evidence however, their oncogenic role remained largely unexplained. Since ETNK1 activity is essential for the synthesis of phosphatidylethanolamine (PE) and given that PE is one of the most abundant phospholipids in the inner membrane of mitochondria, we focused our attention on mitochondrial activity. In order to characterize the oncogenic effect of ETNK1 variants we generated CRISPR/Cas9 clones carrying heterozygous N244S mutation and homozygous ETNK1 deletion (KO cells) on the 293 Flp-In™ cell-line. Both N244S and KO cells showed a significant increase in mitochondrial activity (1.78 and 2.13 fold increase, respectively; p= 0.0096 and p=0.0050) compared to WT, as assessed by MitoTracker™ Red. In line with this finding, electron microscopy revealed a significant modification in mitochondria morphology for N244S and KO cells, changing from an elongated, tubular shape to a round, swollen one. ATP (1.67 and 1.68 fold; p<0.0001; ATPlite Luminescence Assay System) and ROS production (1.66 and 1.74 fold increase; p<0.0001; CellROX™ Green Reagent) were similarly increased. Histone H2AX phosphorylation (γ-H2AX) analysis revealed a higher number of foci in N244S and KO cells (2.60±0.22 and 2.89±0.27; p<0.0001) compared to WT (0.56±0.08). A similar increase in γ-H2AX (3.6 fold; p=0.0037) was present in primary samples from aCML patients carrying ETNK1 mutation compared to ETNK1-WT ones.
In line with these data, a higher mutation rate was detected in N244S and KO cells (8.09*10-7±9.6*10-8 and 8.20*10-7±1.28*10-7; p=0.0060 and p=0.0264) compared to WT (2.98*10-7±8.2*10-8) by 6-thioguanine assay.
The reconstruction of the hierarchy of somatic mutations in ETNK1-mutated aCML patients revealed that ETNK1 variants invariably occur very early in the evolution history of the aCML patients.
Taken together, our results show that impairment of ETNK1 function causes an increase in mitochondrial activity, which in turn leads to increased ROS production driving the accumulation of DNA mutations. Since the characterization of aCML subclonal architecture indicates ETNK1 mutations as a very early event in the history of the disease, we hypothesize that ETNK1 could contribute to the onset of aCML through the activation of a mutant phenotype, which in turn would accelerate the accumulation of further oncogenic mutations.

Abstract
Background Collision tumors are rare entities that consist of two histologically distinct tumor types arising in the same anatomic site. An association between chronic lymphocytic leukemia (CLL) and malignant melanoma (MM) has been already described. Up to now, they have been documented only at positive regional lymph nodes while we focused on collision tumor in a skin lesion. Case presentation We characterized the genomic profile of a skin CLL/MM collision tumor in a patient with a 9-years story of CLL. Typical high-grade genomic biomarkers featured the CLL: the immunoglobulin heavy variable genes were unmutated; a clonal del(11q), involving ATM and BIRC3, was present in the peripheral blood (PB) and skin lesion, while a subclonal large del(13q)/D13S319-RB1 was detected only in the PB. Interestingly, the del(13q) clone, increased from 10% to 46% from diagnosis to relapse. NOTCH1, SF3B1, and TP53 were wild type. The MM lesion carried a BRAFV600E and a TERT promoter mutation. As the family story was consistent with a genetic predisposition to cancer, we performed mutational analysis of genes involved in familial melanoma and CLL, and of BRCA1 and BRCA2. No germinal mutation known to predispose to CLL, MM, or breast cancer was found. Interestingly, conventional cytogenetic detected a constitutional t(12;17)(p13;p13). Conclusions Our data are consistent with distinct genetic landscape of the two tumors which were characterized by specific disease-related abnormalities. CLL cells carried poor prognostic imbalances, i.e. large deletions of the long arm of chromosomes 11 and 13, while in MM cells two functionally linked mutations, i.e. BRAFV600E and a TERT promoter occurred. Although, known germline variations predisposing to MM and/or CLL were ruled out, genetic counseling suggested the proband family was at high risk for MM.

Abstract
We developed a good manufacturing practices-compatible expansion protocol to improve number and purity of regulatory T cells (Tregs) available for clinical trials. Six clinical-grade separation procedures were performed, followed by expansion with high-dose interleukin (IL)-2, anti-CD3/anti-CD28 TCR stimulation, and rapamycin for 19 days achieving a median of 8.5-fold (range, 6.25 to 13.7) expansion. FOXP3 expression was stably maintained over the culture period, while the percentage of CD127 was significantly reduced. The in vitro suppression assay showed a strong Mixed Lymphocytes Reaction inhibition. In vitro amplification did not induce any karyotypic modification. To evaluate the graft-versus-host disease (GVHD)/graft-versus-leukemia (GVL) bifunctional axis, expanded Tregs and conventional T cells (Tcons) were tested in NOD/SCID/IL2Rgnull mice injected with primary acute myeloid leukemia (AML) cells, AML cell line, acute lymphoid leukemia Philadelphia cell line, or Burkitt-like lymphoma cell line. All mice that received leukemia cells together with expanded Tregs and Tcons were rescued from leukemia and survived without GVHD, showing that Treg expansion procedure did not compromise GVHD control and the strong Tcon-mediated GVL activity. This report might represent the basis for treating high-risk leukemia and/or relapsed/refractory leukemia patients with high-dose Treg/Tcons.

Abstract
Recurrent deletions of the long arm of chromosome 5 were detected in 23/200 cases of T-cell acute lymphoblastic leukemia. Genomic studies identified two types of deletions: interstitial and terminal. Interstitial 5q deletions, found in five cases, were present in both adults and children with a female predominance (chi-square, P=0.012). Interestingly, these cases resembled immature/early T-cell precursor acute lymphoblastic leukemia showing significant down-regulation of five out of the ten top differentially expressed genes in this leukemia group, including TCF7 which maps within the 5q31 common deleted region. Mutations of genes known to be associated with immature/early T-cell precursor acute lymphoblastic leukemia, i.e. WT1, ETV6, JAK1, JAK3, and RUNX1, were present, while CDKN2A/B deletions/mutations were never detected. All patients had relapsed/resistant disease and blasts showed an early differentiation arrest with expression of myeloid markers. Terminal 5q deletions, found in 18 of patients, were more prevalent in adults (chi-square, P=0.010) and defined a subgroup of HOXA-positive T-cell acute lymphoblastic leukemia characterized by 130 up- and 197 down-regulated genes. Down-regulated genes included TRIM41, ZFP62, MAPK9, MGAT1, and CNOT6, all mapping within the 1.4 Mb common deleted region at 5q35.3. Of interest, besides CNOT6 down-regulation, these cases also showed low BTG1 expression and a high incidence of CNOT3 mutations, suggesting that the CCR4-NOT complex plays a crucial role in the pathogenesis of HOXA-positive T-cell acute lymphoblastic leukemia with terminal 5q deletions. In conclusion, interstitial and terminal 5q deletions are recurrent genomic losses identifying distinct subtypes of T-cell acute lymphoblastic leukemia.

Abstract
We assessed lineage involvement by NUP98 translocations in myelodysplastic syndromes (MDS), acute myeloid leukaemia (AML), and T-cell acute lymphoblastic leukaemia (T-ALL). Single cell analysis by FICTION (Fluorescence Immunophenotype and Interphase Cytogenetics as a Tool for Investigation of Neoplasms) showed that, despite diverse partners, i.e. NSD1, DDX10, RAP1GDS1, and LNP1, NUP98 translocations always affected a CD34+/CD133+ hematopoietic precursor. Interestingly the abnormal clone included myelomonocytes, erythroid cells, B- and T- lymphocytes in MDS/AML and only CD7+/CD3+ cells in T-ALL. The NUP98-RAP1GDS1 affected different hematopoietic lineages in AML and T-ALL. Additional specific genomic events, were identified, namely FLT3 and CEBPA mutations in MDS/AML, and NOTCH1 mutations and MYB duplication in T-ALL.

Abstract
GNAS1 gene is located at the long arm of chromosome 20 (q13.32). GNAS1 gene deletion has never been investigated in MDS. A GNAS1 activating mutation (R201) was recently found in MDS. We applied FISH and DHPLC plus sequencing to investigate GNAS1 gene in MDS cases with and without del(20q) at karyotype.

Abstract
To provide new insights into the genomic profile of desmoplastic round cell tumors (DSRCT), we applied fluorescence in situ hybridization (FISH) and metaphase comparative genomic hybridization (M-CGH) to two newly diagnosed cases. FISH detected multiple subclones bearing one to three copies of der(11)t(11;22)(p13;q12) and/or der(22)t(11;22)(p13;q12) in both patients. This peculiar genomic imbalance might result from derivative chromosome duplication due to non-disjunction and/or mitotic recombination between normal and derivative chromosomes 11 and 22. Concomitant loss of normal chromosomes (i.e., 11 in patient 1 and 22 in patient 2) caused loss of the WT1 or EWSR1 wild-type allele. M-CGH identified other genomic imbalances: gain at chromosome 3 in both cases and chromosome 5 polysomy in patient 1. Common genomic events (i.e., trisomy 3 and extra EWSR1-WT1 and WT1-EWSR1 copies) probably contributed to disease pathogenesis and/or evolution of DSRCT. Our study demonstrated that an integrated molecular cytogenetic approach identified EWSR1-WT1 cooperating molecular events and genetic markers for prognosis. Thus, FISH and M-CGH might well be applied in a large series of patients to elucidate the genomic background of DSRCT.

Abstract
Multiple lesions in genes that are involved in cell cycle control, proliferation, survival and differentiation underlie T-cell acute lymphoblastic leukaemia (T-ALL). We translated these biological insights into clinical practice to improve diagnostic work-ups and patient management. Combined interphase fluorescence in situ hybridization (CI-FISH), single nucleotide polymorphism (SNP), and gene expression profiles (GEP) were applied in 51 children with T-ALL who were stratified according to minimal residual disease (MRD) risk categories (AIEOP-BFM ALL2000). CI-FISH identified type A abnormalities in 90% of patients. Distribution of each was in line with the estimated incidence in childhood T-ALL: 37.5% TAL/LMO, 22.5% HOXA, 20% TLX3, 7.5% TLX1, and 2.5% NKX2-1. GEP predictions concurred. SNP detected type B abnormalities in all cases, thus linking type A and B lesions. This approach provided an accurate, comprehensive genomic diagnosis and a complementary GEP-based classification of T-ALL in children. Dissecting primary and secondary lesions within MRD categories could improve prognostic criteria for the majority of patients and be a step towards personalized diagnosis.

Abstract
We set up a diagnostic double-color double-fusion fluorescence in situ hybridization (DCDF-FISH) assay to investigate a case of a de novo acute myeloid leukemia (AML)-M4 bearing an inv(11)(p15q22). DCDF-FISH detected the NUP98-DDX10 rearrangement as two fusion signals, at the short and the long arms of the inv(11). Reverse transcription-polymerase chain reaction (RT-PCR) and cloning experiments confirmed the NUP98-DDX10 fusion and identified two splicing fusion isoforms: the known "type II fusion," originating from the fusion of NUP98 exon 14 to DDX10 exon 7 and a new in-frame fusion transcript between NUP98 exon 15 and DDX10 exon 7, which we termed "type III fusion."

Abstract
We investigated TET2 deletion in 418 patients with hematological malignancies. Overall interphase FISH detected complete or partial TET2 monoallelic deletion (TET2(del)) in 20/418 cases (4.7%). TET2(del) was very rare in lymphoid malignancies (1/242 cases; 0.4%). Among 19 positive myeloid malignancies TET2(del) was associated with a 4q24 karyotypic abnormality in 18 cases. In AML, TET2(del) occurred in CD34-positive hematopoietic precursors and preceded established genomic abnormalities, such as 5q- and -7/7q-, which were the most frequent associated changes (Fisher's exact test P=0.000).

Abstract
BACKGROUND Molecular lesions in T-cell acute lymphoblastic leukemias affect regulators of cell cycle, proliferation, differentiation, survival and apoptosis in multi-step pathogenic pathways. Full genetic characterization is needed to identify events concurring in the development of these leukemias. DESIGN AND METHODS We designed a combined interphase fluorescence in situ hybridization strategy to study 25 oncogenes/tumor suppressor genes in T-cell acute lymphoblastic leukemias and applied it in 23 adult patients for whom immunophenotyping, karyotyping, molecular studies, and gene expression profiling data were available. The results were confirmed and integrated with those of multiplex-polymerase chain reaction analysis and gene expression profiling in another 129 adults with T-cell acute lymphoblastic leukemias. RESULTS The combined hybridization was abnormal in 21/23 patients (91%), and revealed multiple genomic changes in 13 (56%). It found abnormalities known to be associated with T-cell acute lymphoblastic leukemias, i.e. CDKN2A-B/9p21 and GRIK2/6q16 deletions, TCR and TLX3 rearrangements, SIL-TAL1, CALM-AF10, MLL-translocations, del(17)(q12)/NF1 and other cryptic genomic imbalances, i.e. 9q34, 11p, 12p, and 17q11 duplication, del(5)(q35), del(7)(q34), del(9)(q34), del(12)(p13), and del(14)(q11). It revealed new cytogenetic mechanisms for TCRB-driven oncogene activation and C-MYB duplication. In two cases with cryptic del(9)(q34), fluorescence in situ hybridization and reverse transcriptase polymerase chain reaction detected the TAF_INUP214 fusion and gene expression profiling identified a signature characterized by HOXA and NUP214 upregulation and TAF_I, FNBP1, C9orf78, and USP20 down-regulation. Multiplex-polymerase chain reaction analysis and gene expression profiling of 129 further cases found five additional cases of TAF_I-NUP214-positive T-cell acute lymphoblastic leukemia. CONCLUSIONS Our combined interphase fluorescence in situ hybridization strategy greatly improved the detection of genetic abnormalities in adult T-cell acute lymphoblastic leukemias. It identified new tumor suppressor genes/oncogenes involved in leukemogenesis and highlighted concurrent involvement of genes. The estimated incidence of TAF_I-NUP214, a new recurrent fusion in adult T-cell acute lymphoblastic leukemias, was 4.6% (7/152).

Abstract
Background NPM1 gene at chromosome 5q35 is involved in recurrent translocations in leukemia and lymphoma. It also undergoes mutations in 60% of adult acute myeloid leukemia (AML) cases with normal karyotype. The incidence and significance of NPM1 deletion in human leukemia have not been elucidated. Methodology and Principal Findings Bone marrow samples from 145 patients with myelodysplastic syndromes (MDS) and AML were included in this study. Cytogenetically 43 cases had isolated 5q-, 84 cases had 5q- plus other changes and 18 cases had complex karyotype without 5q deletion. FISH and direct sequencing investigated the NPM1 gene. NPM1 deletion was an uncommon event in the “5q- syndrome” but occurred in over 40% of cases with high risk MDS/AML with complex karyotypes and 5q loss. It originated from large 5q chromosome deletions. Simultaneous exon 12 mutations were never found. NPM1 gene status was related to the pattern of complex cytogenetic aberrations. NPM1 haploinsufficiency was significantly associated with monosomies (p<0.001) and gross chromosomal rearrangements, i.e., markers, rings, and double minutes (p<0.001), while NPM1 disomy was associated with structural changes (p = 0.013). Interestingly, in complex karyotypes with 5q- TP53 deletion and/or mutations are not specifically associated with NPM1 deletion. Conclusions and Significance NPM1/5q35 deletion is a consistent event in MDS/AML with a 5q-/-5 in complex karyotypes. NPM1 deletion and NPM1 exon 12 mutations appear to be mutually exclusive and are associated with two distinct cytogenetic subsets of MDS and AML.

Abstract
We report a case of adult acute myeloid leukemia with a new t(11;12)(p15;q13) underlying a NUP98 rearrangement without HOXC cluster gene involvement. We designed a specific double-color double-fusion FISH assay to discriminate between this t(11;12)(p15;q13) and those producing NUP98-HOXC11 or NUP98-HOXC13. Our fluorescence in situ hybridization (FISH) showed that putative candidate partners mapping 600 kilobases centromeric to HOXC were RARG (retinoic acid receptor gamma), MFSD5 (major facilitator superfamily domain containing 5), and ESPL1 (extra spindle pole bodies homolog 1). It is noteworthy that so far only ESPL1 has been implicated in human cancers. This FISH assay is useful for diagnostic screening of NUP98-positive leukemias.

Abstract
In this study, we report the molecular cytogenetic characterization of an acute myeloid leukemia with a der(Y)t(Y;1)(q12;q25) in bone marrow cells in a child with Klinefelter syndrome. Conventional cytogenetics demonstrated the unbalanced translocation, i.e., a trisomic 1q25-qter juxtaposed to Yq12 replaced the terminal segment of chromosome Y was acquired and present only on bone marrow cells. Fluorescence in situ hybridization showed that the breakpoint at 1q25 disrupted RABGAP1L, a strongly expressed gene in CFU-GEMM, erythroid cells, and megakaryocytes, while the Yq12 breakpoint fell within the heterochromatic region. As der(Y)t(Y;1)(q12;q25) was an isolated cytogenetic change, RABGAP1L rearrangement as well as gene(s) dosage effects correlated to 1q25-qter trisomy, and Yq12-qter loss may make a major contribution to leukemogenesis and/or disease progression.

Abstract
Transgenic expression of the abnormal products of acute myeloid leukemia-associated (AML-associated) primary chromosomal translocations in hematopoietic stem/progenitor cells initiates leukemogenesis in mice, yet additional mutations are needed for leukemia development. We report here aberrant expression of PR domain containing 16 (PRDM16) in AML cells with either translocations of 1p36 or normal karyotype. These carried, respectively, relatively high prevalence of mutations in the TP53 tumor suppressor gene and in the nucleophosmin (NPM) gene, which regulates p53. Two protein isoforms are expressed from PRDM16, which differ in the presence or absence of the PR domain. Overexpression of the short isoform, sPRDM16, in mouse bone marrow induced AML with full penetrance, but only in the absence of p53. The mouse leukemias were characterized by multilineage cellular abnormalities and megakaryocyte dysplasia, a common feature of human AMLs with 1p36 translocations or NPM mutations. Overexpression of sPRDM16 increased the pool of HSCs in vivo, and in vitro blocked myeloid differentiation and prolonged progenitor life span. Loss of p53 augmented the effects of sPRDM16 on stem cell number and induced immortalization of progenitors. Thus, overexpression of sPRDM16 induces abnormal growth of stem cells and progenitors and cooperates with disruption of the p53 pathway in the induction of myeloid leukemia.

Abstract
Fluorescence in situ hybridization (FISH) and reverse-transcription polymerase chain reaction (RT-PCR) detected the ETV6-PDGFRB fusion in a patient with chronic myelomonocytic leukemia characterized by bone marrow and peripheral blood eosinophilia and a four-way t(1;12;5;12)(p36;p13;q33;q24) on bone marrow cells. The patient consequently underwent imatinib mesylate therapy and achieved hematologic, FISH, and molecular remission. The FICTION technique (fluorescence immunophenotyping and interphase cytogenetics as a tool for the investigation of neoplasms) demonstrated that eosinophils and CD13(+) and CD14(+) cells belong to the neoplastic clone bearing the ETV6-PDGFRB rearrangement. Molecular cytogenetics is the most reliable approach to detect the involvement of promiscuous genes, such as PDGFRB, and to properly classify genetic entities for which targeted therapies are available. Assessment of cell lineages harboring the genomic lesion may contribute in the understanding of leukemogenic pathways.

Abstract
In three patients with acute lymphoblastic leukemia (ALL) and in another with Burkitt lymphoma (BL), conventional cytogenetics and fluorescence in situ hybridization (FISH), applied singly or in combination, showed 1q duplication in two cases of ALL with hyperdiploid karyotypes, 1q duplication resulting from an unbalanced translocation in a third case of ALL, and inv dup(1)(q) in a patient with BL. Centromeric or telomeric breakpoints and extension of the 1q duplicons varied in each case. FISH defined a minimal, common duplicated region of 93kb at band 1q21.2 corresponding to clone RP11-212K13. In this region three putative oncogenes or tumor suppressor genes have been mapped: SF3B4 (splicing factor 3b, subunit 4), OTUD7B (OTU domain containing 7B), and MTMR11 (myotubularin related protein 11). For the first time, a minimal common 1q21.2 duplicated sequence has been identified in lymphoid malignancies in a region where putative oncogenes or suppressor genes have been mapped. This finding elucidates the genomic background of ALL and BL with 1q duplication and provides the basis for molecular studies investigating which genes are involved in leukemogenesis or disease progression in these cases.

Abstract
In hematologic malignancies chromosome aberrations generating fusion genes include cryptic deletions. In a patient with acute myeloid leukemia and normal karyo-type we discovered a new cryptic 9q34 deletion and here report the cytogenetic and molecular findings. The 9q34 deletion extends 2.5 megabases and juxtaposes the 5' TAF-I to the 3' CAN producing a TAF-I/CAN fusion gene. TAF-I/CAN transcribes into two fusion proteins bearing either TAF-Ialpha or TAF-Ibeta moieties. We set up molecular assays to monitor the chimeric TAF-Ialpha/CAN and TAF-Ibeta/CAN transcripts which, after hematopoietic stem cell transplantation from an HLA-identical sibling, were no longer detected.

Abstract
We investigated genetically affected leukemic cells in FIP1L1-PDGFRA+ chronic eosinophilic leukemia (CEL) and in BCR-ABL1+ chronic myeloid leukemia (CML), two myeloproliferative disorders responsive to imatinib. Fluorescence in situ hybridization specific for BCR-ABL1 and for FIP1L1-PDGFRA was combined with cytomorphology or with lineage-restricted monoclonal antibodies and applied in CML and CEL, respectively. In CEL the amount of FIP1L1-PDGFRA+ cells among CD34+ and CD133+ cells, B and T lymphocytes, and megakaryocytes were within normal ranges. Positivity was found in eosinophils, granulo-monocytes and varying percentages of erythrocytes. In vitro assays with imatinib showed reduced survival of peripheral blood mononuclear cells but no reduction in colony-forming unit growth medium (CFU-GM) growth. In CML the BCR-ABL1 fusion gene was detected in CD34+/CD133+ cells, granulo-monocytes, eosinophils, erythrocytes, megakaryocytes and B-lymphocytes. Growth of both peripheral blood mononuclear cells and CFU-GM was inhibited by imatinib. This study provided evidence for marked differences in the leukemic masses which are targeted by imatinib in CEL or CML, as harboring FIP1L1-PDGFRA or BCR-ABL1.

Abstract
In a patient with chronic lymphocytic leukemia (CLL) molecular cytogenetics showed terminal del(14)(q24). Fluorescence in situ hybridisation (FISH) narrowed the deletion to a 35 megabases DNA segment, with the proximal breakpoint between two partially overlapping clones, RP1-116J24 and RP5-1119N5. Besides loss of material at 14q24-qter, comparative genomic hybridisation (CGH) showed loss of 3p21.3-pter, 4p11-p15.1, 8p12-pter, 13q12-q14, and 15q11-q15, and gain of 3q25-qter. Del(13)(q12-14) included the RB-1 gene but not D13S319 and D13S25 loci. The patient was refractory to fludarabine and rituximab. Our findings and data from other reports suggest del(14)(q24) is indicative of aggressive course and is closely associated with del(13)(q14) in CLL.

Abstract
Fluorescence in situ hybridization and comparative genomic hybridization characterized 6p rearrangements in eight primary and in 10 secondary myeloid disorders (including one patient with Fanconi anemia) and found different molecular lesions in each group. In primary disorders, 6p abnormalities, isolated in six patients, were highly heterogeneous with different breakpoints along the 6p arm. Reciprocal translocations were found in seven. In the 10 patients with secondary acute myeloid leukemia/myelodysplastic syndrome (AML/MDS), the short arm of chromosome 6 was involved in unbalanced translocations in 7. The other three patients showed full or partial trisomy of the 6p arm, that is, i(6)(p10) (one patient) and dup(6)(p) (two patients). In 5/7 patients with unbalanced translocations, DNA sequences were overrepresented at band 6p21 as either cryptic duplications (three patients) or cryptic low-copy gains (two patients). In the eight patients with cytogenetic or cryptic 6p gains, we identified a common overrepresented region extending for 5-6 megabases from the TNF gene to the ETV-7 gene. 6p abnormalities were isolated karyotype changes in four patients. Consequently, in secondary AML/MDS, we hypothesize that 6p gains are major pathogenetic events arising from acquired and/or congenital genomic instability.
