2. Cytogenetics And Chromosomal Disorders Cytogenetics and chromosomal disorders. Core information about cytogeneticsand chromosomal disorders is presented in the following topics http://arbl.cvmbs.colostate.edu/hbooks/genetics/medgen/chromo/

Genetics Index Glossary Cytogenetics and Chromosomal Disorders Cytogenetics is the study of normal and abnormal chromosomes. This includes examination of chromosome structure, learning and describing the relationships between chromosome structure and phenotype, and seeking out the causes of chromosomal abnormalities. In the simplest case, chromosomes are examined and characterized by obtaining an individual's karyotype, which is a description of the number and structure of the chromosomes. All species are affected by chromosomal disease. Its manifestations are diverse and numerous, including early embryonic death, minor to major congenital defects, development of cancer, and infertility or sterility. A broad base of knowledge is necessary in order to understand, diagnose and advise about this important class of diseases. Core information about cytogenetics and chromosomal disorders is presented in the following topics: Chromosome Structure and Terminology Preparing a Karyotype Aneuploidy and Deletions Translocations ... Overview of Chromosomal Disease Advanced and supplemental topics related to cytogenetic and chromosomeal disease are: Chromosome Numbers in Different Species Last updated on December 08, 1996

4. Overview Of Chromosomal Disease The concepts on incidence presented above refer to the broad spectrumof chromosomal disorders. Causes of chromosomal disorders. http://arbl.cvmbs.colostate.edu/hbooks/genetics/medgen/chromo/chromo_dis.html

Genetics Index Glossary Overview of Chromosomal Disease Cytogenetic abnormalities are common in all species. The best data on incidence have been collected from humans, and that information seems to be very similar to what appears to be happening in other animals. Incidence and Significance Both the overall incidence, and the occurrence of specific abnormalities clearly depend upon when the data are collected relative to development. This bias is clearly understood by considering the effect on survival of minor versus major genetic lesions. For example, when newborn children are screened, it is found that roughly 1 in every 200 has a chromosomal abnormality. Some of these children are phenotypically normal, while others have obvious, sometimes severe manifestations of disease. By definition however, these children have chromosomal disorders at the "mild" end of the spectrum because they are compatible with survival to term. A much higher incidence of chromosomal disease is seen if one looks earlier in gestation. Approximately half of the human fetuses that are spontaneously aborted during the first trimester are chromosomally abnormal, reflecting chromosomal disorders severe enough to disrupt prenatal development. If one looks at chromosomes in preimplantation embryos, even higher numbers of abnormalities are seen: 5-10% of viable blastocysts collected from cattle and pigs were cytogenetically abnormal. Finally, some chromosomal abnormalities are essentially never seen, presumably because they are so profound as to cause death shortly after fertilization.

There are two main types of chromosomal abnormality which may occur during meiosis and fertilisation. These are known as structural aberrations and numerical aberrations. If a chromosome or piece of a chromosome is missing or duplicated, there are missing or extra genes respectively. When a person has missing or extra information (genes) problems can develop for that individual's health and development. A chromosomal abnormality occurs when there is a defect in a chromosome or in the arrangement of the genetic material on the chromosome. Chromosomal abnormalities give rise to specific physical features, but it should be stressed that there may be wide variations in the severity of the symptoms in individuals with the same chromosome abnormality.

Human Chromosomal Disorders April 30, 2003 Readings: Web Notes Only! I. Karyotype Analysis of Human Chromosomes Karyotype preparation and analysis Cells (from blood, amniotic fluid, etc) are grown in vitro (in a cell culture dish) to increase their number Cell division is then arrested in metaphase with colchicine (prevents mitotic spindle from forming) Cells are centrifuged and lysed to release chromosomes Chromosomes are stained, photographed, and grouped by size and banding patterns This is a photograph of the 46 human chromosomes in a somatic cell, arrested in metphase. Can you see that they are duplicated sister chromatids 2. Normal male karyotype (a Cytogeneticist has lined these chromosomes up, matching homologues up and arranging them by size) 3. Normal female karyotype II. Alterations in chromosome number: Nondisjunction occurs when either homologues fail to separate during anaphase I of meiosis, or sister chromatids fail to separate during anaphase II. The result is that one gamete has 2 copies of one chromosome and the other has no copy of that chromosome. (The other chromosomes are distributed normally.) If either of these gametes unites with another during fertilization, the result is

Chromosomal Disorders What are chromosomal disorders? What kinds of chromosomal disorders are there? Down syndrome is a relatively common chromosome abnormality with which many people are familiar. It results from having three copies of chromosome number 21, so it also called trisomy 21. People with Down syndrome almost always have some degree of mental retardation and often have a wide variety of other medical problems. Although these medical problems can be treated, there is no treatment or cure for the underlying chromosomal disorder. Individuals with Down syndrome have an average life expectancy of over 50 years but usually cannot live independently. How likely is it that my baby has Down syndrome? Probability of Down Syndrome Less than 30 Less than 1:1000 Are there other chromosomal disorders besides Down syndrome? Yes. Some are more severe than Down syndrome: the most important example is trisomy 18. Affected individuals can be profoundly retarded and are often stillborn or die in infancy due to the serious medical problems that are associated with these conditions. Fortunately, these severe chromosomal disorders are much less common at birth than Down syndrome. Also, the structural defects that are associated with these conditions are often recognized at an ultrasound done after 16 weeks. There are also chromosomal disorders that have manifestations that are milder than Down syndrome. They are relatively common, but are not associated with mental retardation or major physical handicap. Affected individuals may have infertility and possible learning and/or behavioral problems.
