Karyotypes of 107 cases with adult T-cell leukemia/lymphoma (58 male, 49 female; 81 acute or lymphoma type, 26 chronic or smoldering type) were reviewed by a panel of cytogeneticists and were correlated with the subtypes of the disease. Clonal chromosome abnormalities were found in 103 (96%) cases, of which four had hypotetraploidy. Of 184 numerical abnormalities in the remaining 99 cases with ...
OBJECTIVE To review clinical validation or implementation studies of maternal blood cell-free (cf) DNA analysis in screening for aneuploidies and to explore the potential use of this method in clinical practice. METHODS Searches of PubMed and MEDLINE were performed to identify all peer-reviewed articles on cfDNA testing in screening for aneuploidies between 2011, when the first such study was...
Chronic myelomonocytic leukemia (CMML) is a rare hematopoietic malignancy of childhood. To define the clinical and hematologic characteristics of the disease, we performed a retrospective analysis of 110 children given the diagnosis CMML irrespective of karyotype. Median age at diagnosis was 1.8 years. Neurofibromatosis type 1 was known in 14% and other clinical abnormalities in 7% of the child...
Herein, the first case of childhood erythrophagocytosis following chemotherapy for erythroleukemia in a child with monosomy 7 is reported. A 5-year-old boy presented with anemia, thrombocytopenia, and hepatosplenomegaly in whom erythroleukemia was diagnosed. Prolonged pancytopenia accompanied by persistent fever and huge splenomegaly and hepatomegaly became evident after 2 courses of chemothera...
Monosomy of an autosome is widely thought to be lethal (Patau, I963). Deficiencies due to deletions of chromosomes I8 and 5 are well documented (de Grouchy, Lamy, Thieffry, Arthuis, and Salmon, I963; Lejeune, Lafourcade, Berger, Vialatte, Boeswillwald, Seringe, and Turpin, I963), and reciprocal translocations which can arise in a carrier person and result in unbalanced offspring with duplicatio...
Turner syndrome is a sex-chromosome disorder; occurring in 1 in 2,500 female births. There are sporadic few case reports of concomitant Turner syndrome with schizophrenia worldwide. Most Turner females had a 45,X monosomy, whereas the majority of comorbidity between Turner syndrome and schizophrenia had a mosaic karyotype (45,X/46,XX). We present a case of a 21-year-old woman with Turner syndro...
Turner syndrome (TS) is a relatively common chromosomal disorder caused by complete or partial X monosomy. The most frequently observed karyotype, 45, X, arises more often by loss of the paternal X or Y chromosome in meiosis or in early embryogenesis than by loss of the maternal X chromosome. The main clinical features of TS are short stature, gonadal dysgenesis, and not to undergo pubertal dev...
