Chromosome Analysis, Blood

Some chromosomal disorders that may be detected include Down Syndrome, Edwards Syndrome, Patau Syndrome, Klinefelter Syndrome, Turner Syndrome, and Chronic myelogenous leukemia.

The examples of chromosomal abnormalities include Trisomy, Monosomy, Deletions, Duplications, Translocations, and Genetic rearrangement. In trisomy, there is presence of an extra chromosome which means that instead of two, three chromosomes are present. The diseases which are associated with trisomy include Down syndrome, Patau syndrome, Edward syndrome, and Klienfelter syndrome. In monosomy, there is an absence of one of the chromosomes such as in Turner syndrome. In the case of deletions, there are missing pieces of chromosomes or genetic material. In the case of duplications, there is presence of extra genetic material which can be present on any chromosome. In the case of translocations, pieces of chromosomes break off and get reattached to chromosomes. In the case of genetic rearrangement, the genetic material is present on a chromosome, but it is not present in its normal location.
