Clinicians provide advice on genetic testing and interpretation of genomic data. Conditions seen include:

  • Diagnostic opinion for children with undiagnosed malformation syndromes and conditions associated with intellectual disabilit
  • Diagnostic testing of rare diseases and syndromes including rapid genomic testing in critically ill children
  • Genetic counselling for families with known genetic and chromosomal conditions - this includes risks in future pregnancies and the need for testing of other family members
  • Genetic counselling prior to prenatal testing (invasive, non-invasive and PIGD)
