Preparatory Mindset

Study this chapter with focus on how genetic principles affect clinical practice.

Core Concepts

• Confidentiality: Genetic information is protected health information. Cannot disclose to family without patient consent.


• HIPAA: Health Insurance Portability and Accountability Act — genetic info cannot be used to deny health insurance


• Duty to warn: Geneticist may have obligation to inform at-risk relatives in some circumstances


• Testing children: Generally deferred for adult-onset disorders until child can consent (no medical benefit during childhood)


• Eugenics: Historical movement to 'improve' human population through selective breeding → forced sterilizations, unethical


• Genetic discrimination: Use of genetic information to deny insurance, employment — prohibited by GINA (Genetic Information Nondiscrimination Act)


• Adverse selection: Individuals concealing increased genetic risk when applying for insurance


• Informed consent: Required for ALL genetic testing — must include discussion of risks, benefits, limitations


• Reproductive compensation: Parents having additional children to 'replace' a child lost to genetic disease

High-Yield Points

• Genetic info = protected health information (HIPAA, GINA)


• Children: no testing for adult-onset disorders unless medical benefit


• Eugenics = historical abuse; modern genetics is patient-centered and non-directive

Topic Summary

Ethical practice in genetics requires balancing patient confidentiality with potential duties to at-risk relatives, while protecting against discrimination.
