A new recurring chromosome abnormality was identified in 8 of 621 consecutive successfully karyotyped adults with de novo acute leukemia. These eight patients had trisomy 13 as the sole cytogenetic abnormality. On central morphologic review, five cases were classified as subtypes of acute myeloid leukemia, one as acute mixed lymphoid and myeloid leukemia, one as acute lymphoid leukemia, and one...

Isoji Sasagawa, MD, Department of Urology, School of Medicine, Yamagata University, 2-2-2 Iidanishi, Yamagata-shi, Yamagata 990-23 (Japan) Dear Sir, Sex chromosome abnormality is one of the representative causes of male infertility. Previously, various types of the abnormality have been reported [1, 2]. Patients with the abnormality usually show gonadal dysfunction [3]. Similar dysfunction was ...

Veterinary cytogenetics is an area of genetics that deals with normal or abnormal chromosomes of animals. Chromosome abnormalities in cattle can cause significant adverse effects on fertility through failure of production of viable gametes or early embryonic death that consequently leads to great economic loss. Chromosomal aberrations can occur as numerical errors or structural rearrangements u...

We recently described, in Cannabis sativa, the oldest sex chromosome system documented so far plants (12–28 Myr old). Based on estimated age, we predicted that it should be shared by its sister genus Humulus, which is known also to possess XY chromosomes. Here, used transcriptome sequencing of an F1 family H. lupulus identify and study chromosomes this species using probabilistic method SEX-DET...

A 32 week, small for dates baby with aplasia cutis congenita had an unbalanced translocation, being monosomic for distal 12q and trisomic for distal 1q. As far as is known, the association between extensive skin defects and a chromosomal abnormality has not been reported before. Keratin genes have been located in a different area of 12q, but this case may indicate other candidate areas to explo...

Background and Objectives: studying chromosomal changes for anemia patients of children age (3month-12years ) in the city kut diagnosing those abnormalities resulting from having Methods: The chromosomes Patients to were analyzed studied using cytogenetic analysis detect aberrations caused by after collecting blood samples Al-Karama Teaching Hospital as well clinics Kut.Results: Chromosomal all...

The aim of this study was to evaluate the relationship between fetal karyotype and parental chromosomal abnormalities, and to provide a basis for clinical diagnosis and therapy in Northeast China. A total of 144 spontaneously aborted fetuses were analyzed by FISH to test for chromosome number and to recall couples for peripheral blood karyotype analysis. The rate of abnormal chorionic villus ch...

XX male is a kind of sexual differentiation disorder that affects one out of every 20,000 to 25,000 male births. The patients have male phenotypes with female chromosomes, the karyotype 46XX. More than 150 XX males have been reported in the medical literature since Albert de la Chapelle first reported a male human with a pure XX sex chromosome constitution in 1964.1,2 Most patients with this co...
