TS occurs in about 1 in 2,000 female births worldwide. The reason for the missing or changed X chromosome appears to be a random event, so
any girl could be born with TS. What are the physical features of Turner syndrome?
The features of TS can vary widely from patient to patient, so the condition may not be diagnosed until a girl reaches the age of puberty
or even later. The most common features of TS are short stature (with
an average adult height of about 4’8”, if untreated) and ovaries that do
not produce female hormones or eggs. As adults, most women with TS
cannot become pregnant without medical help.
