Who we treat

The Clinical Genetics Service provides genetic assessment, counselling and genomic testing for children, adults, and couples during pregnancy if there is a suspected diagnosis or a risk for inheriting an inherited disorder.

We consult on a wide range of genetic conditions including cystic fibrosis, thalassaemia, Huntington's disease and chromosome problems. One of our common referral groups are children with learning difficulties or developmental delay where a genetic basis is suspected or confirmed.

Our team

Genetic health professionals include clinical geneticists, who are doctors with a specialisation in genetic diagnosis and management, and genetic counsellors who provide information and support to individuals, couples and families regarding health concerns which are inherited or suspected as having a genetic cause. Genetic counselling is provided to promote informed choices and adaptation to a diagnosis or a risk of inheriting a genetic disorder. Our team also provides access to genetic testing, resources and research.

Prenatal Genetics Clinic Every pregnant woman in New South Wales is offered tests during her pregnancy to monitor the health of the baby and to screen for signs of specific chromosome conditions. If a prenatal screen result indicates an increased risk for a chromosome condition, a genetic counsellor can help support couples in making informed decisions about the option of additional tests available during pregnancy. For more information about prenatal screening and diagnostic tests, see the NSW Health’s Centre for Genetics Education Prenatal Testing Booklet
Porphyria Clinic

There are eight different types of porphyria which are all caused by a build up of porphyrins in the cells of the body. Porphyrins are substances that are required for the production of red blood cells. For more information on porphyria, please visit the Australian Porphyria Association.

Your appointment

All referrals to the Clinical Genetics Service are reviewed and triaged. Patients are contacted directly by a genetic counsellor to arrange an appointment. 

What happens at a clinical genetics appointment? 

A clinical genetics appointment may take up to one hour. During this time, a clinical geneticist or genetic counsellor will collect your personal medical history as well as a detailed family medical history. A physical examination may be required, and clinical photographs may be taken. 

Information, including photographs, collected during your appointment is recorded in your genetic file, which is separate to the main hospital medical record. Information from your genetic file may not be shared without your consent. Find out more about the privacy of patient information here.

What to bring to your (or your child's) appointment? 

  • Referral letter from your doctor 
  • Medicare card 
  • Any relevant medical test results or letters from other doctors and specialists 
  • Family photographs, for example, baby and childhood photos (of parents too if your child has been referred) 

Genetic testing 

Genetic testing can be a complex process and may not be helpful in every circumstance. At your appointment we will discuss the availability of genetic testing and the potential advantages, disadvantages and limitations of testing. If testing is undertaken, this usually requires a blood test. 

Telehealth consultation 

You may be provided with the option of a Telehealth consultation for your genetic clinic appointment. If you have agreed to a Telehealth consultation, a link will be emailed to you prior to the appointment. You may be provided with a My Virtual Care link, which is a NSW Telehealth service. A genetic counsellor will help you connect for the appointment.

Where to find us

The location of your appointment will be communicated to you via letter or email. Most appointments take place RPA Hospital Main Building (Building 75) on:

  • Level 5 – Women’s and Babies Ambulatory Care Clinic rooms 
  • Level 5 – Fetal Medicine Unit 
  • Level 6 – Cardiovascular Ambulatory Care Clinic rooms

Please check in and present your Medicare card at the front desk on arrival.
