Genetic mosaicism
Mosaicism Definition
Genetic mosaicism – Mosaicism related to a condition where an individual has two or more cell populations that differ in genetic makeup. This situation can affect any type of cell, including blood cells, gametes (egg and sperm cells), and skin.
Mosaicism may be detected through chromosome evaluation. Mosaicism is usually described as a percentage of the cells examined. The normal chromosome finding in males is 46 XY and normal in females is 46 XX. Mosaicism Causes is a result of an error in cell division very early in fetal development.
Chromosomal mosaicism example such as:
- Turner Syndrome Mosaic
- Klinefelter Syndrome Mosaic
- Down Syndrome Mosaic
Mosaicism Symptoms is vary from person to person and are very difficult to predict. When there are normal cells as well as abnormal cells, associated abnormalities may not be as severe. You still need exams and tests to be repeated for confirmation and to help further define the type and severity of the genetic mosaicism. If you have it, the treatment will depend on the specific type of genetic disease. Patients with mosaicism may require less intense treatment than those with the typical form of the disease (with 100% of their cells affected), because they may be more mildly affected (only some of their cells are abnormal).
Possible Complications that couse mosaicism like signs and symptoms above, vary with both the type and percentage of cells affected by the genetic change. You need Contact a Medical Professional if you have Mosaicism Symptoms, because there is currently no known prevention for mosaicism.
