Abstract
The inv (4)(p13q13) cytogenetic abnormality is uncommon in hematologic malignancies. So far, it has not been previously reported in patients with essential thrombocythemia (ET). We report a first case of ET with inv (4)(p13q13) karyotype in a 69-year-old female patient who developed myelofibrosis at follow up. Conventional cytogenetic analysis from a bone marrow sample showed 46, XX, inv (4)(p13q13) [3]/46, XX [4] at diagnosis and subsequent analysis revealed the same abnormal karyotype during the myelofibrosis phase (46, XX, inv (4)(p13q13) [13]/46, XX [26]). The prognostic significance of this chromosomal abnormality is unknown.

Abstract
We report the case of a 61-year-old woman who presented with a myelodysplastic syndrome (MDS) and a t(5;7)(q11.2;p15) in her bone marrow cells. Subsequent analysis of phytohemagglutinin-stimulated peripheral blood lymphocytes and cultured skin fibroblasts showed that the translocation was constitutional. Disruption of chromosome bands 5q11.2 and 7p15 has been described recurrently in MDS and acute myelocytic leukemia (AML) and, although the age of onset was not earlier than usual, it is nonetheless possible that genes interrupted by this translocation may been a predisposing factor for her condition. With progression to AML, a further rearrangement of the constitutional der(7)t(5;7) occurred, involving chromosome arm 1q. Fluorescence in situ hybridization (FISH) with whole-chromosome paints showed that the result of the second rearrangement, a t(1;7)(q32.1;q32), was observed, leading to trisomy of the segment 1q32.1 approximately qter and monosomy of the segment 7q32.1 approximately qter. The acquired imbalances, particularly loss of 7q, are commonly associated with MDS/AML and a poor prognosis; however, this patient remained in remission after treatment for more than two years before AML relapse, perhaps because the affected regions fall outside of the critical regions of imbalance.

Abstract
A predisposition to tumor development is associated with some constitutional chromosomal abnormalities. Investigations of families with an apparent hereditary cancer and constitutional chromosome rearrangements have led to the molecular identification of tumor suppressor genes. Under the somatic mutation theory for the development of cancer, two mutational events are required. The first step may be a constitutional event and the second an acquired genetic mutation. Cytogenetic studies were performed on 5633 bone marrow specimens from patients with hematologic malignancies from a single institution. Fifty cases of constitutional chromosome aberrations were detected. Data collected from the literature and from our series are reviewed and compared with the incidence of specific constitutional chromosome aberrations in the newborn population. Possible mechanisms that may predispose individuals with constitutional chromosome aberrations to the development of a hematologic malignancy are reviewed.

Abstract
An inversion, inv(4)(p14q27), was found as the sole karyotypic anomaly at diagnosis in the bone marrow cells from a 65-year-old male patient with an M4 acute nonlymphocytic leukemia (ANLL). To our knowledge, the breakpoints observed in this case appear to be different from other inversions of chromosome 4 previously described in ANLL. The patient we described had a poor response to chemotherapy and had a short survival.

Abstract
We have reviewed 4164 patients with various hematologic disorders cytogenetically studied in our laboratory during the last 25 years to analyze the frequency of constitutional chromosome aberrations (CCA) and to evaluate their association with hematologic malignancies. Our population of patients included 1133 pediatric patients and 3031 adults. Twenty-four (0.58%) cases showed CCA. They included four patients with Robertsonian translocations, one patient with a balanced translocation, two patients with sex chromosome abnormalities, and 17 cases with Down syndrome (DS). Nonsignificant differences among the frequency of patients with CCA from our hematologic series and those observed in the two largest combined surveys of livebirth published (0.65-0.84%) were found. The incidence of DS patients in our population (0.41%) was approximately three times higher than of that observed at birth (0.12-0.17%; P<0.001). The total incidence of constitutional chromosome abnormalities in the non-DS hematologic patients was 0.168% (7 of 4164) lower than of that observed in the newborn population (0.51-0.67%; P<0.001). Nonsignificant differences were found when the incidences of structural aberrations and sex chromosome anomalies were individually compared with the data of the overall population. Our results suggest that the presence of a CCA, other than DS, would not predispose patients to hematologic malignancies.

Abstract
We report four cases of unrelated adult males carrying constitutive balanced pericentric inversions of chromosome X (one case), chromosome 2 (one case), and chromosome 5 (two cases) and presenting with myeloid malignancies. We discuss the potential contribution of these abnormalities to a background of susceptibility to hematologic malignancies.
