Trisomy 18, mosaicism (mitotic nondisjunction) - what does this mean
Trisomy 18, mosaicism (mitotic nondisjunction) is a chromosomal disorder in which there are three copies of chromosome 18, or portions of it, instead of the normal two copies. this occurs when the chromosomes fail to separate properly during cell division, resulting in an extra chromosome being present in the cells. this condition is more common in females than males, and is usually caused by a random error in cell division during the formation of the egg or sperm.
What happens during the disease - trisomy 18, mosaicism (mitotic nondisjunction)
Trisomy 18 mosaicism (mitotic nondisjunction) is a genetic disorder caused by the presence of an extra copy of chromosome 18 in some or all of the cells of the body. this extra copy of chromosome 18 results from a mistake in cell division called nondisjunction, which occurs during the formation of reproductive cells (eggs and sperm) in a parent or during the development of the embryo. in some cases, the extra copy of chromosome 18 is only present in some cells, resulting in a mosaic of normal and abnormal cells. this type of trisomy 18 is referred to as trisomy 18 mosaicism.
Trisomy 18, mosaicism (mitotic nondisjunction) - Prevention
The best way to prevent trisomy 18, mosaicism (mitotic nondisjunction) is to practice safe and healthy lifestyle habits, such as eating a balanced diet, exercising regularly, avoiding smoking and alcohol, and getting regular prenatal care. additionally, genetic counseling can help identify any potential risk factors and provide information about the condition.
