Turner Syndrome

What is Turner Syndrome?

Turner syndrome is a genetic disorder that affects females. It occurs when a baby has a missing or incomplete X chromosome. It may take one of three forms:
  • missing an entire X chromosome (most common)
  • two X chromosomes, but one that is incomplete
  • some cells with two X chromosomes, and others with only one

Girls who are missing only part of a chromosome usually have milder symptoms.

Turner syndrome can cause a wide variety of symptoms that affect a range of organs, including the heart, eyes, ears, bones and kidneys. Most girls with Turner syndrome are born with poorly formed or missing ovaries, which can result in a failure to reach puberty and infertility. Many are also short in stature.

Turner syndrome occurs in about one out of every 2,500 females.
