Genetic privacy is a critical concern in bioethics because human genomes are not uniquely individual; they are shared with family members. Consequently, information derived from an individual's DNA inherently reveals sensitive health and trait data about their relatives.1

This interconnectedness creates significant ethical dilemmas regarding privacy and autonomy. If genetic information is not properly safeguarded, it risks being misused by third parties—such as employers, government agencies, or health-insurance companies—to discriminate against individuals or their families based on their genetic predispositions.23

Ethically, society must strive to harness the benefits of genetics, such as predictive and preventative medicine, while upholding the fundamental principle of protecting individuals from unfair treatment. Because genetic data can expose the vulnerabilities of loved ones, maintaining strict confidentiality is essential to ensure that scientific progress does not come at the cost of personal rights or family well-being.132
