Unbalanced whole-arm translocations (WATs) of the long arm of chromosome 1, resulting in complete trisomy 1q, are chromosomal abnormalities detectable in both solid tumors and hematologic neoplasms. Among the WATs of 1q to acrocentric chromosomes, a few patients with der(1;15) described as a dicentric chromosome have been reported so far, whereas cases of der(1;14) are much rarer. We report on a case of der(1;14) detected as single anomaly in a patient with myelodysplastic syndrome. The aim of our work was to investigate the breakpoints of the (1;14) translocation leading to the der(1;14). Fluorescence in situ hybridization (FISH) experiments have been performed on chromosome preparations from bone marrow aspirate, using specific centromeric probes of both chromosomes, as well as a probe mapping to 1q11 band. FISH results showed that in our patient the derivative chromosome was monocentric with a unique centromere derived from chromosome 14. The breakpoints of the translocation were located in the short arm of chromosome 14 and in the long arm of chromosome 1, between the alphoid D1Z5 and the satellite II domains. The 1q breakpoint was within the pericentromeric region of chromosome 1, which is notoriously an unstable chromosomal region, involved in different chromosomal rearrangements. Copyright © 2012 S.

Are there gender differences in prevalence, surgical results and long-term survival of patients with congenital heart disease? Available literature data allow us to state what follows. At birth there is a mild but significant prevalence of congenital heart disease in females. The most severe congenital heart diseases are less frequent in girls, but when they are present in females, they are linked to a higher surgical mortality rate, due perhaps to lower weight at birth and to the prevalence of extracardiac malformations and/or of associated genetic syndromes. On the other hand, in adults, surgery for congenital heart disease is at higher risk in males, and so the longterm survival rate is higher in females. Particular psychological attitudes, a higher incidence of pulmonary hypertension, as well as specific problems linked to the reproductive function characterize congenital heart disease in adult women. The knowledge and analysis of these data are essential for a correct management of congenital heart disease in neonates, children and adults. © 2013 Il Pensiero Scientifico Editore.

We describe a 6-year-old boy with a de novo 12 Mb interstitial duplication of chromosome 17q11.1q12, identified by oligo array-CGH. The patient shows psychomotor developmental and language delay, dolicocephaly, minor facial anomalies, hypotonia and renal megacalicosis. The duplication involves the neurofibromatosis type I (NF1) gene and overlaps with long-range unusual deletions of the NF1 region, extending over 17q12 region and associated with renal cysts and diabetes (RCDA). To our knowledge this is the first case of a patient carrying a large-sized duplication involving the 17q11.2q12 region. In the duplicated chromosomal segment there are about 130 annotated genes. Among them, several genes which have been already proposed as candidate for mental retardation (MR) in patients with partially overlapping deletions may be responsible for neurological impairment in our patient. In addition, other genes within the duplicated region are of interest for possible correlation with a few clinical features of the patient. © 2010.
