Rare diseases: the liaison office and the official registry

Last reviewed: August 25, 2026VerifiedSalud

In short

Act 9-2025 creates the Liaison Office for the Support and Registry of Persons with Rare Diseases, attached to the Puerto Rico Department of Health, with the purpose of compiling, maintaining and updating an official registry of persons with rare diseases on the Island, facilitating access to precise diagnoses and innovative treatments, and coordinating efforts with specialised national and international entities. The law defines rare diseases as those health conditions recognised by the Office of Rare Diseases Research through the Genetic and Rare Diseases Information Center, and orphan drugs as those drugs or biological products intended to prevent, diagnose or treat rare diseases whose low prevalence limits their development and investment, recognised by the Federal Food, Drug, and Cosmetic Act and the Orphan Drug Act. Among the Liaison Office’s functions are advising the Secretary of Health on public policy; creating and maintaining the Official Rare Diseases Registry; facilitating access to specialised medical services, therapies and orphan drugs; providing orientation to patients, families and health professionals; establishing cooperation agreements with research centres, universities and hospitals inside and outside Puerto Rico; fostering scientific and clinical studies; developing economic, social and psychological support and assistance programmes for patients and their caregivers; and implementing educational campaigns. The collection and use of the Registry’s data shall be subject to strict confidentiality and personal data protection rules. The Office shall be directed by an Executive Director appointed by the Secretary of Health and shall have personnel specialised in medicine, social work, legal counselling and administrative functions. A five-member Advisory Committee chaired by the Secretary of Health is also established.

What is it?

It is the law that gives a named door to a problem that usually has none: a Liaison Office inside the Department of Health, dedicated to people with rare diseases. Its value is in what the law orders it to do: orient patients, families and health professionals; facilitate access to specialised services, therapies and orphan drugs; and develop economic, social and psychological support programmes for patients and caregivers. It also creates an official registry, with confidentiality required by law.

Who can do it?

The law sets no eligibility criteria and no enrolment procedure. What it does define is what counts as a rare disease: “those health conditions recognised by the Office of Rare Diseases Research through the Genetic and Rare Diseases Information Center.” That definition points to a federal source, not to a Puerto Rico list, which is why we do not publish a list of conditions here.

Step by step

  1. Step 1: There is an office with a name and an owner

    It is the first thing it solves, because in rare diseases the problem is usually that nobody knows whom to call. “The Liaison Office for the Support and Registry of Persons with Rare Diseases is established, which shall be attached to the Puerto Rico Department of Health.” It is directed by an Executive Director appointed by the Secretary of Health, and the law provides it shall have personnel specialised “in areas such as medicine, social work, legal counselling and administrative functions.”

  2. Step 2: What it owes you

    Of the list of functions, these are the ones with a patient’s face: “facilitate access to specialised medical services, therapies and orphan drugs”; “provide orientation to patients, families and health professionals about rare diseases and their available treatments”; and “develop economic, social and psychological support and assistance programmes for patients and their caregivers.” The last expressly includes caregivers, who are almost never named in a law.

  3. Step 3: What counts as a rare disease

    The definition matters because it decides the scope, and it points to a federal source: rare diseases means “those health conditions recognised by the Office of Rare Diseases Research through the Genetic and Rare Diseases Information Center.” There is no Puerto Rico list of its own in the law’s text.

  4. Step 4: What an orphan drug is

    The law defines it and anchors the definition in two federal statutes, which helps when speaking with a health plan or a pharmacy. Orphan drugs means “those drugs or biological products intended to prevent, diagnose or treat rare diseases, whose low prevalence limits their development and investment,” and adds: “Those recognised by the Federal Food, Drug, and Cosmetic Act, 21 U.S.C. §§ 301-399 (1938) and the Orphan Drug Act, 21 U.S.C. §§ 360AA-360FF (1983) are considered such.”

  5. Step 5: The registry, and its confidentiality

    The law creates the Official Rare Diseases Registry, which “shall contain detailed and updated information about the patients diagnosed with these conditions” and shall be used “for planning and executing public health strategies, as well as for coordinating scientific research and developing patient support policies.” And it sets a limit in its own article: “The collection and use of data in the Official Registry shall be subject to strict confidentiality and personal data protection rules, in accordance with current legislation.”

  6. Step 6: Who advises, and why it matters to you

    Because there is a seat for patient organisations. The Rare Diseases Advisory Committee is made up of five members: the Secretary of Health, who chairs it; a geneticist; “one (1) representative of patient organisations”; an academic with research or public health policy experience; and a health professional with clinical experience managing rare diseases. The Committee advises on the design, implementation and evaluation of public policy “and may issue recommendations for the adoption of new measures or programmes.”

  7. Step 7: Outside Puerto Rico too

    A detail that matters when the diagnosis or treatment is not on the Island. Among the Office’s functions is “establishing cooperation agreements with research centres, universities and specialised hospitals inside and outside Puerto Rico,” and also “fostering the development of scientific and clinical studies on rare diseases on the Island.”

  8. Step 8: What this law does not do

    Worth saying before someone arrives expecting something else. The law creates an office, a registry and a committee; it creates no enforceable right to a treatment or a medicine, sets no eligibility criteria, and provides no claim procedure and no penalty. If your problem is a health plan denying you a medicine, that route is a different one and has its own guide here.

Where to do it

The Liaison Office is attached to the Department of Health, and that is where it lives under the law: it is directed by an Executive Director appointed by the Secretary of Health. The law publishes no address, phone or registry enrolment form, and we do not invent them. If your immediate matter is a health plan denying a medicine, or coverage of a condition, those have their own guides here; if it is the newborn screening that detects hereditary conditions at birth, so does that.

How long it takes

The law sets no service times for the patient. It does order the Department of Health to adopt the regulations necessary for the law’s effective implementation within a term of no more than one hundred twenty (120) days of its approval.

What to do if something goes wrong

What we do not publish, and why. We do not publish an address, phone, hours or registry enrolment form: the law names none and we do not guess contact details. We do not publish a list of rare diseases: the law refers the definition to the Genetic and Rare Diseases Information Center of the Office of Rare Diseases Research, a federal source we did not verify for this guide. We do not publish eligibility criteria or service times: the law sets none; that is why cost is left unverified and time reports only the regulatory deadline. We did not read the regulations the Department of Health must adopt within one hundred twenty (120) days. And we say it plainly: this law creates no enforceable right to a treatment or a medicine, and no forum for claiming. A note on the source: we read the Department of State certified copy, which is a scan; its text layer carries optical recognition errors, so we quote only what reads without ambiguity.

Common mistakes

  • Expecting this law to force coverage of a treatment: it creates an office, a registry and a committee, not an enforceable right.
  • Not asking for the orientation: the law imposes it on the Office for patients, families and health professionals.
  • Forgetting caregivers: the law orders developing economic, social and psychological support and assistance programmes for patients and their caregivers.
  • Assuming there is a Puerto Rico list of rare diseases: the definition points to the Genetic and Rare Diseases Information Center.
  • Fearing for the registry’s privacy without knowing the article: the law subjects it to strict confidentiality and personal data protection rules.
  • Ruling out help from outside the Island: the Office may establish agreements with centres, universities and hospitals inside and outside Puerto Rico.
