Our clinical genetics service provides care for people and families with a range of genetic conditions. Genetic conditions are caused by changes in a person's genetic information which may be passed down in families.

We support people with:

  • genetic and genomic testing
  • diagnosis of a genetic condition if appropriate
  • management of a genetic condition where necessary
  • risk assessments and advice for relatives
  • genetic counselling and testing for a condition in a family
  • emotional and psychosocial support

We run clinics with other health professionals to manage symptoms or risks from a genetic condition.

We're also a leading centre for pre-implantation genetic diagnosis (PGD.
