Turner Syndrome

Turner syndrome (TS) is a congenital condition (present from birth) that only affects people assigned female at birth (AFAB). It happens when one of two of the X chromosomes is missing, either partially or completely.

Turner syndrome leads to a variety of features and symptoms and affects each person differently. But short stature and reduced ovary functioning (primary ovarian insufficiency) are the two most common features.

How common is Turner syndrome?

Turner syndrome affects 1 in 2,000 to 1 in 2,500 babies assigned female at birth. It’s the most common sex chromosome-related condition that affects babies AFAB.
