| Karyotype Genetic Test : What is a karyotype test? A karyotype test is a type of genetic testing. It looks at the size, shape, and number of chromosomes in a sample of cells from your body. Chromosomes are tiny "packages" in your cells that contain your genes. Genes carry information, called DNA, that controls what you look like and how your body works. Normally, all your cells (except for egg and sperm cells) have a set of the same 46 chromosomes. The chromosomes are grouped into 23 pairs. Each pair has two chromosomes, one coming from each parent. A karyotype test checks the chromosomes in your cells to: - See whether you have a full set of 46 chromosomes. Having too many or too few chromosomes can cause serious problems with health, growth, and normal development, such as Down syndrome (extra chromosome 21),Turner syndrome (missing X chromosome), and various genetic disorders. - Look for changes in the structure of chromosomes, such as broken, missing, or extra parts. These changes may cause a wide variety of problems depending on which chromosome is affected. But some changes in chromosomes don't cause problems. Certain chromosome problems are present from birth, while others can develop in certain cells later in life. Those that develop later in life can cause specific types of cancer.
