The bases of DNA are adenine (A), thymine (T), guanine (G), and cytosine (C).

The integration of genetic information into clinical practice, such as through electronic health records, presents significant privacy and security challenges. Because our genomes are shared with family members, genetic data is inherently sensitive, as information about one individual can reveal details about their relatives.12

Key privacy and ethical concerns include:

Data Security: Breaches in health information systems could lead to the unauthorized release of personal health data and sensitive genetic information.1
Genetic Discrimination: There is a critical need to protect individuals against discrimination based on their genetic makeup, which could potentially impact areas such as employment or insurance.3
Autonomy and Misuse: The power of genetic information carries the risk of misuse, necessitating a commitment to protecting individual autonomy and diversity.2
Reproductive Decisions: Genetic testing can lead to complex dilemmas regarding reproductive choices, which some may view as forms of genetic selection.3

It is a fundamental ethical imperative to harness the benefits of human genetics to improve health while strictly safeguarding the privacy and rights of all individuals.2
