Turner syndrome is a rare genetic condition in which a female does not have the usual pair of X chromosomes.
Bonnevie-Ullrich syndrome; Gonadal dysgenesis; Monosomy X; XO
The typical number of human chromosomes is 46. Chromosomes contain all of your genes and DNA, the building blocks of the body. Two of these chromosomes, the sex chromosomes, determine if you become a boy or a girl.
In Turner syndrome, cells are missing all or part of an X chromosome. The condition only occurs in females. Most commonly, a female with Turner syndrome has only 1 X chromosome.
