Ethical, Legal, and Social Issues in Genetics
Core concepts
Understand informed consent, confidentiality, privacy, and the return of results - including incidental/secondary findings and the patient's right to opt in or out. Know GINA (US Genetic Information Nondiscrimination Act) protections for health insurance and employment, and its limits (does not cover life, disability, or long-term care insurance; does not cover all employers). Be familiar with HIPAA and the Common Rule for research.
Know duty to warn vs confidentiality (e.g., disclosure to at-risk relatives), minors and predictive testing (usually deferred for adult-onset conditions), reproductive autonomy, prenatal and preimplantation testing ethics, eugenics history, and equity/access issues. Understand genetic counseling principles: nondirectiveness, autonomy, and informed decision-making.
Traps
Questions often overstate GINA's scope - it does not protect against life/disability insurance discrimination. Another trap: assuming a duty to warn relatives overrides confidentiality in all cases; disclosure is generally limited and guided by policy and law. Watch for predictive testing in minors - generally deferred unless actionability in childhood exists. Also, beware of conflating research consent with clinical consent.
Rule of thumb
GINA covers health insurance and employment - not life, disability, or long-term care. When in doubt about disclosure, prioritize the patient's confidentiality and use counseling to support voluntary family disclosure.
Worked example
A patient with a BRCA1 pathogenic variant declines to inform relatives. The clinician should respect confidentiality, offer counseling and a family letter, and disclose only where a specific legal duty applies.
