Mosaicism

Alternate Names : Chromosomal Mosaicism, Gonadal Mosaicism

Definition

A person who is a "genetic mosaic" has cells in his or her body with different genetic makeup.

This usually is a variation in the number of chromosomes in the body's cells. Normally, all body cells would have the same number of chromosomes (46). But in mosaicism, some cells may have 47 chromosomes (such as extra chromosome 21 or X chromosome in some, but not all cells).
