Health professional information

The Department of Genetic Medicine at Westmead Hospital provides clinical genetics consultations for the assessment, investigation, diagnosis, management and monitoring of rare genetic disorders for adults.

We also provide genetic counselling as part of ongoing patient management and are involved in the transition of care from paediatric services for patients with known genetic disorders.

Service overview

We provide clinical genetics services for adults within two main domains:

  • general clinical genetics
  • genetic metabolic disorders

Our multidisciplinary service incorporates genetic counselling, nursing and dietetic care.

As a primarily ambulatory specialty, we work closely with GPs for the continued care of our patients. We have also established links with patient advocacy groups.

We also liaise closely with the Clinical Genetics Services at the Children’s Hospital at Westmead to provide a timely prenatal genetics service here at Westmead Hospital. Additionally, we are involved in the transition of care from paediatric services for patients with known genetic disorders.

Although we are not a laboratory/pathology service, we play a significant role in the facilitation of genetic and state-of-the-art genomic and biochemical testing.
