Summary
Professional guidance that helps families understand inherited disease risk and testing options.
In depth
Counsellors take a family history, explain inheritance patterns, calculate risks, and discuss tests and options in a non-directive way. They support decisions with ethical considerations such as autonomy and privacy.
Typical situations include carrier screening, prenatal diagnosis and predictive testing for late-onset disease.
The process includes a family history, risk assessment, information about the condition, discussion of testing, reproductive options (prenatal diagnosis, preimplantation genetic testing, donor gametes, adoption) and support. Counsellors respect autonomy and confidentiality, and follow principles of informed consent.
Testing raises ethical issues: when to test children for adult-onset conditions, how to deal with incidental findings, duties to inform relatives, and protection from discrimination (the US Genetic Information Nondiscrimination Act of 2008 covers insurance and employment but not life insurance). Direct-to-consumer tests give results that may be hard to interpret without support.
Example: a woman with a BRCA1 variant may choose surveillance, preventive surgery or medication, after discussion of her risks.
