Turner syndrome | Symptoms and Causes

What are the symptoms of Turner syndrome?

The symptoms of Turner syndrome can vary from girl to girl, depending on how much of the X chromosome is missing and which part is missing.

The most obvious symptom of Turner syndrome is a shorter than normal height. Girls with Turner syndrome usually have a decrease in growth percentiles starting between ages 4 and 6.

Other symptoms of Turner syndrome can include:
  • feeding problems during infancy
  • puffy hands and feet at birth, as well as a wideness and "webbing" of the neck
  • a low hairline at the back of the neck
  • minor differences in the shape and position of ears
  • a broad chest with widely spaced nipples
  • an increased number of small brown moles (called nevi) on the skin
  • frequent ear infections
  • sparse public hair
  • incomplete breast development
  • inability to menstruate
  • vaginal dryness
  • skeletal problems
  • problems with spatial perception, non-verbal memory and attention

What are the causes of Turner syndrome?

Turner syndrome is caused by a missing or incomplete X chromosome. It is not known why this occurs, but it is believed to occur randomly.
