Who to refer?

Relatives of a patient known to have a mutation in a gene known to increase cancer risk such as BRCA1, BRCA2 or any of the genes associated with Lynch Syndrome (MLH1, MSH2, MSH6 or PMS2). This type of testing is known as “predictive” genetic testing. It is helpful to enclose a copy of the affected relative’s genetic test results with the patient’s referral or to encourage the patient to bring this along to their appointment at the Genetics Clinic.
For guidance on who to refer if a genetic predisposition
has not been identified in a family, please see below:
