What federal law regulates the protection of personal information in registries?

The Health Insurance Portability and Accountability Act (HIPAA) is the correct choice because it establishes national standards for the protection of certain health information. HIPAA is particularly relevant to registries that handle personal health data, ensuring that personal information is not disclosed without the individual's consent. This law sets forth privacy rules and security standards that govern how personal health information can be used and shared, which is crucial in maintaining the confidentiality and integrity of sensitive data in any registry related to health information.

In contrast, the other options focus on different types of information or populations. The Family Educational Rights and Privacy Act (FERPA) pertains to the privacy of student education records; the Children's Online Privacy Protection Act (COPPA) protects the personal information of children under age 13 online; and the Gramm-Leach-Bliley Act (GLBA) addresses the protection of consumers' personal financial information. While each of these laws has its purpose, they do not specifically regulate personal information in registries related to health or medical data like HIPAA does.
