Other information about Turner Syndrome

  • Would need regular health checks but can lead a healthy lifestyle
  • Life expectancy may be slightly reduced
  • On most occasions intelligence is average, some may have learning difficulties (not extreme)

Genetics of Turner Syndrome

  • In most cases Turner syndrome is not inherited. 
  • The chromosomal abnormality occurs as a random event during the formation of reproductive cells (eggs and sperm) in the affected person's parents.
  • An error in cell division (nondisjunction) can result in reproductive cells with an abnormal number of chromosomes.
  • Although rare, Turner syndrome caused by partial deletion can be passed from one generation to the next.
