What is a key consideration when handling genomic data to protect participants?

• A. Data sharing should be unrestricted to maximize collaboration.
• B. Psychosocial risks must be ignored.
• C. Privacy protections and data sharing restrictions must be in place.
• D. There is no obligation to consider consent for data sharing.

Answer: (C)

Protecting participants when handling genomic data hinges on implementing privacy protections and data-sharing controls. Genomic information is highly identifiable and can reveal not only an individual’s health risks but also information about relatives; even de-identified data can sometimes be re-identified. Therefore, robust privacy safeguards—such as careful data de-identification where feasible, controlled-access repositories, data-use agreements, and clear governance—are essential, along with obtaining appropriate consent for how data will be shared and used. This approach balances advancing research with respecting participants’ autonomy and privacy.

Unrestricted data sharing would disregard these privacy risks. Psychosocial risks aren’t something to ignore, as participation and data sharing can impact individuals and families. And there is indeed an obligation to consider consent for data sharing and to apply appropriate restrictions based on what participants have consented to and what safeguards are in place.
