Abnormal Karyotypes

In my first book (Your Easy Way To Chromosomes), the main topic was about the human chromosomes, their structures, abnormalities, syndromes, and chromosome analysis. In this book I focused on abnormal karyotypes and how chromosomal abnormalities happen. A karyotype is a picture of a person's chromosomes from body cells (blood, hair, or any other tissue), photographing them through a microscope and arranging them in pairs, ordered by size and position of centromere for chromosomes of the same size. Karyotype test (alternative names are Chromosome Analysis, Chromosomal Analysis) plays a role in: diagnosis genetic diseases which are related to chromosomal abnormalities, diagnosis some birth defects, and provides clinical utility in the diagnosis and treatment of hematologic malignancies. On the other hand some genetic abnormalities cannot be detected by karyotype analysis such as microdeletions. Karyotype helps clinical cytogeneticist to identify abnormalities by: Counting the number of chromosomes and looking for extra chromosome such as in trisomy 21 or missing chromosome in a karyotype such as in Turner syndrome. Looking for changes in chromosome structure such as chromosomal deletions, duplications, translocations, insertions, inversions and other chromosomal abnormalities.

Chromosomes are vital components of genetic material, and, as such, distruption or changes to the structure of chromosomes can result in different health problems and deficits. This book explains chromosomal abnomalities and their effects on living organisms, including humans and plants. Classical and molecular cytogenetics techniques have a considerable number of potential applications, especially in clinical trials and biomedical diagnosis, making them a strong and insightful complement to other molecular and genomic approaches. Chapters cover topics including Down syndrome, fetal ultrasounds, acute myeloid leukemia, and Phelan-McDermid syndrome, among others.

A guide to identifying disease processes in the placenta affecting pregnancy outcome, with current diagnostic criteria and clinical consequences.

Chromosome Identification—Technique and Applications in Biology and Medicine contains the proceedings of the Twenty-Third Nobel Symposium held at the Royal Swedish Academy of Sciences in Stockholm, Sweden, on September 25-27,1972. The papers review advances in chromosome banding techniques and their applications in biology and medicine. Techniques for the study of pattern constancy and for rapid karyotype analysis are discussed, along with cytological procedures; karyotypes in different organisms; somatic cell hybridization; and chemical composition of chromosomes. This book is comprised of 51 chapters divided into nine sections and begins with a survey of the cytological procedures, including fluorescence banding techniques, constitutive heterochromatin (C-band) technique, and Giemsa banding technique. The following chapters explore computerized statistical analysis of banding pattern; the use of distribution functions to describe integrated profiles of human chromosomes; the uniqueness of the human karyotype; and the application of somatic cell hybridization to the study of gene linkage and complementation. The mechanisms for certain chromosome aberration are also analyzed, together with fluorescent banding agents and differential staining of human chromosomes after oxidation treatment. This monograph will be of interest to practitioners in the fields of biology and medicine.

The fourth edition of this well-known text provides students, researchers and technicians in the area of medicine, genetics and cell biology with a concise, understandable introduction to the structure and behavior of human chromosomes. This new edition continues to cover both basic and up-to-date material on normal and defective chromosomes, yet is particularly strengthened by the complete revision of the material on the molecular genetics of chromosomes and chromosomal defects. The mapping and molecular analysis of chromosomes is one of the most exciting and active areas of modern biomedical research, and this book will be invaluable to scientists, students, technicians and physicians with an interest in the function and dysfunction of chromosomes.

Within 10 chapters this book addresses the whole gamut of questions that may arise in the context of pregnancy resulting from assisted reproduction. Incidence of abortion, extrauterine pregnancy or chromosomal abnormalities, pregnancy complications, problems regarding mode of delivery and the health status of children at birth are covered as well as the further development of the children and the social structure of the families. Topics such as follow-up of families in lesbian relationships and following gamete donations are also discussed.
