What causes Turner’s syndrome?
Turner syndrome occurs when part or all of an X chromosome is missing from most or all of the cells in a girl’s body. A girl normally receives one X chromosome from each parent. The error that leads to the missing chromosome appears to happen during the formation of the egg or sperm.
How does mosaic Turner syndrome occur?
Mosaic Turner syndrome is also not inherited. In an affected individual, it occurs as a random event during cell division in early fetal development. As a result, some of an affected person’s cells have the usual two sex chromosomes, and other cells have only one copy of the X chromosome.
