Whole chromosome monosomy, mosaicism (mitotic nondisjunction) - what does this mean
Whole chromosome monosomy is caused by a mitotic nondisjunction event in which one of the two copies of a chromosome is not distributed correctly during cell division, resulting in mosaicism with some cells having one copy of the chromosome and others having two copies.
What happens during the disease - whole chromosome monosomy, mosaicism (mitotic nondisjunction)
Whole chromosome monosomy, mosaicism (mitotic nondisjunction) is a disorder caused by a chromosomal abnormality in which an individual has only one copy of a particular chromosome instead of the normal two copies. this occurs when there is failure of the two sets of chromosomes to separate during cell division, resulting in a cell with only one copy of the chromosome. this condition can cause a wide range of physical and intellectual impairments depending on the chromosome affected.
Whole chromosome monosomy, mosaicism (mitotic nondisjunction) - Prevention
Whole chromosome monosomy and mosaicism (mitotic nondisjunction) can be prevented by avoiding environmental risk factors such as exposure to radiation, certain chemicals, and drugs. additionally, women should take folic acid supplements before and during pregnancy to reduce the risk of chromosomal abnormalities. genetic counseling before and during pregnancy can also help to identify and reduce the risk of chromosomal abnormalities.
