Counselling

COMPREHENSIVE GENETIC SCREENING, TESTING, COUNSELLING, AND SPECIALIST GENETIC CONSULTATION SERVICES ARE AVAILABLE AT THE PRACTICE.

3% of babies are born with a congenital disorder or “birth defect”. Many of these conditions have an underlying genetic cause or contribution. Consultation with a genetic counsellor or medical geneticist can provide you with more information about the diagnosis, its cause, the inheritance pattern, recurrence risk, further investigations, and available management options during and after your pregnancy.

What is a medical geneticist?

A medical geneticist, or clinical geneticist, is a medical doctor who specialises in the diagnosis, investigation, and management of genetic or hereditary conditions presenting throughout every stage of life. Medical Geneticists may consult with women or couples before, during or after their pregnancy, and with newborns, children, and adults who either have or are at risk of a genetic condition or syndrome. In the prenatal setting, a medical geneticist will assist with the diagnosis, investigation, and interpretation of genetic testing results within the context of your personal history, family history, findings on prenatal ultrasound and examination of your baby following delivery.

What is a genetic counsellor?

A genetic counsellor is a health care professional who works as part of a multidisciplinary team in assisting to diagnose, manage, predict and screen for genetic conditions. They do this by taking and analyzing family history information, assessing the risks of inheriting or passing on a medical condition, ordering and interpreting genetic test results and explaining these to the individual patient and their relatives. Being well-versed in genetic aspects of medical conditions, a genetic counsellor provides information to those who are at an increased risk of either having an inherited disorder or of passing it on to their children. A genetic counsellor provides information on the inheritance and recurrence risks of disorders; addresses the concerns of patients, their families, and their health care providers; and supports patients and their families dealing with these disorders. 

 

During pregnancy, patients are referred to a genetic counsellor if their baby is found to have a potential birth defect or genetic condition. A genetic counselor helps expecting parents to understand the medical information, what to expect, how to prepare and the options available to them. They also facilitate the genetic testing process from deciding on the most appropriate and cost-effective testing to the result delivery and post-result delivery counselling if needed.
