Electron microscopic investigations of surface spread synaptonemal complexes in spermatocytes from a 37-year-old man ascertained for infertility detected a pericentric inv(1), and subsequent lymphocyte analysis placed the breakpoints at p32 and q42. Most spermatocytes showed a maturation arrest at mid-pachytene explaining the azoospermia. As in two other(More)
Probe YNZ22 (D17S5) is a highly polymorphic, variable number tandem repeat (VNTR) marker previously shown to be deleted in all patients with the Miller-Dieker syndrome (MDS) but not in patients with isolated lissencephaly sequence (ILS). Primers were constructed to the unique sequence flanking the polymorphic, repetitive region of YNZ22 for amplification by(More)
Classic cytogenetic and comparative genomic hybridisation (CGH) data on osteosarcomas have been reported extensively in the literature. However, the number of paediatric osteosarcoma cases studied below the age of 14 years remains relatively small. This study reports four new cases of paediatric osteosarcoma in patients aged 3 to 13 years, evaluated by(More)
We report a 27-year-old man with HIV-1 infection who developed acute promyelocytic leukemia (APL) with a novel complex three-way chromosomal translocation t(15;16;17). Induction of remission and consolidation with all-trans-retinoic acid (ATRA)- and anthracycline-based chemotherapy was followed by maintenance therapy consisting of ATRA, 6-mercaptopurine(More)
We describe a complex and unique, de novo apparently balanced translocation involving chromosomes 4, 18, and 21 with 4 breakpoints, in a patient who was referred for an evaluation of possible fragile-X syndrome. Fluorescence in situ hybridization (FISH) confirmed the complexity of the rearrangement and showed the derivative 21 to be composed of 3 distinct(More)
We report a case of transient myeloproliferative disorder (TMD) in a neonate without features of Down syndrome (DS) with clonal karyotype evolution, after apparent spontaneous resolution of TMD, but eventually progressing to acute megakaryoblastic leukemia (AMKL). The patient had petechiae, thrombocytopenia, and blastemia. Trisomy 21 with a satellited Y(More)
Interstitial deletion of the short arm of chromosome 1 is rare. Eleven different breakpoints have been described in 12 children. We report a patient with del(1)(p32.1p32.3). Only one of the previously reported patients had an apparent identical deletion to that of the present case. The phenotypes of the two patients are strikingly similar. Distinctive(More)
We report on a family ascertained through a 14-month-old girl with a terminal deletion of chromosome 8p23.1. Analysis of the karyotype of other relatives showed that the mother is the carrier of a balanced complex 4-break chromosome rearrangement, which she and her brother inherited from their father following recombination. This complex chromosome(More)
Low-grade fibromyxoid sarcoma (previously known as Evans tumor) is a rare soft tissue neoplasm characterized by a deceptively bland appearance despite the potential for late metastasis or recurrence. We describe a 13-year-old patient with a popliteal fossa mass initially thought to be benign that, because of array-comparative genomic hybridization findings(More)
