What is mosaicism?
Mosaicism is when an individual has two or more genetically different sets of cells in their body. After fertilization, a mistake during DNA replication and/or cell division can result in mosaicism. There are various degrees of mosaicism, and the significance of its effect is impacted by the degree as well as the severity of the original mistake itself.
