How is mosaic trisomy 8 inherited?

Chromosomal mosaicism is when some cells of the body have an extra or missing chromosome while other cells in the body have the typical 46 chromosomes. This may happen because of a change or mistake that occurs in either the sperm or egg at conception. This change causes the cells to have an extra chromosome. Usually, the change is new to the child, meaning that neither parent has mosaic trisomy 8. There are some instances where one of the parents has a chromosome rearrangement called a translocation, which increases the risk to have a child with mosaic trisomy 8.
