What is Down's syndrome

  • Down's syndrome is when you're born with an extra chromosome. This can affect how your body and brain develops.
  • You usually get an extra chromosome by chance, because of a change in the sperm or egg before you're born. This change does not happen because of anything anyone did before or during pregnancy.
  • People with Down's syndrome are likely to have some level of learning disability. This means they'll have a range of abilities. Some people will be more independent and do things like get a job. Other people might need more regular care.
  • Like everyone, people with Down's syndrome have their own personalities, things they like and dislike and things that make them who they are.
  • Screening tests for Down’s syndrome are offered to everyone who is pregnant to find out how likely it is the baby has the condition. It’s your choice whether or not to have the screening.
  • The chance of having a baby with Down’s syndrome increases as you get older, but anyone can have a baby with Down’s syndrome.
