- Respects individual autonomy and self-determination by ensuring individuals have the right to make informed decisions about their genetic information
- Requires providing comprehensive genetic counseling to help individuals understand the complex implications of test results (risk assessment, treatment options)
- Ensures voluntariness and freedom from coercion, allowing individuals to make decisions freely without undue influence from family members, healthcare providers, or societal pressures
- Protects the confidentiality and privacy of highly personal and sensitive genetic information through measures that prevent unauthorized access (secure databases, encryption)
Genetic discrimination impacts
- Can lead to employment discrimination where employers use genetic information to make hiring, promotion, or termination decisions, resulting in job loss and financial hardship (denied promotions, wrongful termination)
- Enables insurance discrimination where health insurers deny coverage or charge higher premiums based on genetic predispositions (pre-existing conditions)
- Results in where individuals with certain genetic conditions face reduced opportunities and quality of life due to stigma and social isolation (ostracism, bullying)
- Requires legal protections like the (GINA) that prohibit discrimination based on genetic information in employment and health insurance, but do not cover life, disability, or long-term care insurance
Ethical Challenges in Genetic Testing Results and Implications
Incidental findings challenges
- Involve genetic information unrelated to the primary purpose of the test that may reveal predispositions to untreatable or late-onset conditions (Huntington's disease, Alzheimer's)
- Require healthcare providers to balance the duty to inform patients with the potential for and anxiety when deciding whether to disclose incidental findings
- Need to respect patient autonomy and individual preferences in deciding whether to receive incidental findings information
- Present challenges in interpreting and communicating the implications of findings that have uncertain clinical significance or lack effective interventions (variants of unknown significance)
Prenatal testing implications
- Support reproductive autonomy by providing parents with the right to make informed decisions about their pregnancies based on genetic information
- Raise concerns about and discrimination, as selective abortion based on genetic conditions may devalue the lives of individuals with disabilities and reinforce societal stigma
- Pose slippery slope risks where prenatal genetic testing could lead to the selection of traits unrelated to health, creating "designer babies" and exacerbating social inequalities (intelligence, physical attributes)
- Can have psychological impacts on parents, who may experience guilt, grief, and doubt when deciding to terminate a pregnancy based on genetic information
Key Terms to Review (19)
Biopiracy: Biopiracy refers to the unauthorized and exploitative appropriation of biological resources and traditional knowledge from indigenous communities, often by corporations or researchers, without proper compensation or consent. This practice raises ethical concerns about cultural exploitation, intellectual property rights, and the sustainability of biodiversity.
Corporate Social Responsibility: Corporate social responsibility (CSR) refers to the ethical practice where businesses consider their impact on society, the environment, and the economy while making decisions. It emphasizes accountability and proactive efforts to enhance community well-being, promote sustainable practices, and maintain transparency with stakeholders.
Data ownership: Data ownership refers to the legal rights and control over data, including who has the authority to manage, use, and share that data. In the context of genetic testing and screening, data ownership raises important ethical questions regarding patient privacy, consent, and the potential for misuse of sensitive genetic information. It involves considerations of who benefits from the data, how it is stored and protected, and the implications for individuals when their genetic data is shared or sold.
Deontological ethics: Deontological ethics is a moral theory that emphasizes the importance of following rules or duties in determining ethical behavior, rather than focusing solely on the consequences of actions. This approach asserts that some actions are inherently right or wrong, regardless of their outcomes, and it is often associated with philosophers like Immanuel Kant, who advocated for duty-based morality.
Disability rights: Disability rights refer to the legal and human rights that ensure individuals with disabilities have the same opportunities and protections as those without disabilities. These rights advocate for accessibility, inclusion, and equal treatment in society, aiming to eliminate discrimination and promote the dignity of people with disabilities. This concept is crucial in discussions surrounding genetic testing and screening, as advancements in biotechnology can raise ethical concerns about how individuals with disabilities are perceived and treated within society.
Ethical stewardship: Ethical stewardship refers to the responsibility of individuals and organizations to manage resources, including human and genetic information, in a way that respects ethical principles and promotes the welfare of society. This concept emphasizes accountability, transparency, and a commitment to doing what is right, especially in contexts where decisions can significantly impact individuals' lives, such as genetic testing and screening.
Genetic Information Nondiscrimination Act: The Genetic Information Nondiscrimination Act (GINA) is a federal law enacted in 2008 that prohibits discrimination based on genetic information in health insurance and employment. GINA aims to protect individuals from being treated unfairly by employers or insurers due to their genetic predispositions, which can be revealed through genetic testing and screening. This law plays a critical role in addressing ethical concerns surrounding genetic privacy and potential misuse of genetic data in the context of healthcare and employment decisions.
