The test accurately determines whether an individual has the mutated gene. All testing programs are offered in conjunction with genetic counselling. Down syndrome 1 in 700 Chromosomal Maternal serum screening established in 1996 for all pregnant women to determine risk. Further diagnostic tests required to confirm test. Polycystic kidney disease 1 in 1,200 Autosomal dominant Mutated gene identified.
Affected families can have pre-pregnancy counselling and prenatal testing.
Studies on families in which many close relatives are affected with the same type of cancer have enabled the detection of the gene responsible, particularly for breast and colon cancer. A number of specialised cancer genetic counselling and testing centres have been established around Australia. General cancer genetic clinics where the emphasis is on diagnosis, risk assessment and surveillance strategies for a wide spectrum of cancers and, where appropriate, genetic testing. Colorectal Cancer Genetic Service Commencing in late 1996, this service will be piloted over three years. It will be carefully monitored and evaluated by the management group from the VCGS, ACCV and Royal Melbourne Hospital.
