variant - (pronounced) (VAYR-ee-unt) Any change in the DNA sequence of a cell. Variants can be caused by errors during cell division or exposure to DNA-damaging agents in the environment. Variants can be harmful, useful, or ineffective. If they are found in cells that produce eggs or sperm, they can be inherited; if variants occur in other cell types, they are not inherited. Certain variants can lead to cancer or other diseases. A variant is sometimes called a mutation
