Trisomy 16 mosaicism was found in amniotic fluid cells in a patient undergoing amniocentesis because of elevated second-trimester maternal serum alpha-fetoprotein (MSAFP) (2.80 MOM), a markedly elevated human chorionic gonadotropin level (hCG) (12.02 MOM), and a Down syndrome risk of 1:55. Ultrasound evaluation of the fetus indicated the presence of an(More)
A case of a multiply malformed liveborn infant with mosaic tetraploidy on examination of bone marrow but not of peripheral lymphocytes or skin fibroblasts is presented. The literature is reviewed and the clinical features of our patient are compared with those of the nine previously reported cases. We suggest that when the clinical suspicion of polyploidy(More)
Deletion of a portion of the short arm of chromosome 7 is associated with a recognizable phenotype which often includes craniosynostosis. Recent reports have suggested that craniosynostosis occurs only if there is a deletion involving band 7p21 or the segment distal to that band. We report on a boy who had an interstitial deletion of 7p, not involving band(More)
Herein, we describe a case of a female patient in whom B cell chronic lymphocytic leukemia (CLL) and mantle cell lymphoma (MCL) were diagnosed simultaneously. She presented with anemia, thrombocytopenia and splenomegaly. Flow cytometry demonstrated two immunophenotypically distinct CD5-positive monoclonal B cell populations. Peripheral blood fluorescence in(More)
The development of probes containing segments of DNA from chromosome region 15q11-q13 provides the opportunity to confirm the diagnosis of Prader-Willi syndrome (PWS) and Angelman syndrome (AS) by fluorescence in situ hybridization (FISH). We have evaluated FISH studies and high resolution chromosome banding studies in 14 patients referred to confirm or(More)
