Turner syndrome (TS), also known as 45,X, or 45,X0, is a genetic condition in which a female is partly or completely missing an X chromosome. Signs and symptoms vary among those affected.
What are other names for Turner syndrome?

How did Turner syndrome get its name?
Turner syndrome is named for Henry Turner who, in 1938, was one of the first doctors to report on the disorder in the medical literature. Turner syndrome is one of the most common chromosomal disorders and likely the most common genetic disorder of females.
Does Turner syndrome come from Mom or Dad?
Turner syndrome is not caused by anything the parents did or did not do. The disorder is a random error in cell division that happens when a parent’s reproductive cells are being formed. Girls born with the X condition in only some of their cells have mosaic Turner syndrome.
Why can’t males have Turner syndrome?
Turner syndrome is caused by a female having one normal X chromosome in each of her cells , while the other sex chromosome is either missing or structurally abnormal. Females without Turner syndrome have 2 full X chromosome in all of their cells, and males have one X chromosome and one Y chromosome .
