Researchers at the National Human Genome Research Institute are starting a study to understand rare genetic diseases by studying people from countries outside the United States. The study will look at how genetic changes cause unusual disease patterns in different populations. This research could help doctors better understand and diagnose rare diseases worldwide.
WHY IT MATTERSThis trial expands rare disease research beyond US populations, which means genetic discoveries could help patients globally who have been underrepresented in previous studies.

This is a research study looking for patients and families affected by rare diseases to share their thoughts and values about brain and nerve-related medical decisions. Researchers at St. Jude Children's Research Hospital want to understand what matters most to people living with rare diseases so they can make better ethical decisions in medical research and treatment. The study is now accepting participants and will start in April 2026.
WHY IT MATTERSThis study gives rare disease patients and caregivers a direct voice in shaping how medical ethics and brain-related research decisions are made — your input could influence future treatment guidelines and research practices.

This study is looking for 2,800 people to help researchers understand how being a caregiver affects a person's health and stress levels over time. The study includes caregivers of people with rare diseases like Batten disease, Tay-Sachs disease, and other inherited metabolic disorders, as well as caregivers of people with undiagnosed diseases. By learning more about caregiver stress, researchers hope to find ways to better support the millions of unpaid family caregivers in the U.S.
WHY IT MATTERSIf you or a family member care for someone with a rare inherited metabolic disorder, Batten disease, Tay-Sachs, or an undiagnosed disease, this study directly addresses the health challenges caregivers face and could lead to better support resources.

Researchers are looking for 63 participants to help them understand how DNA changes in babies before birth compare to DNA changes after birth. They want to collect DNA from amniotic fluid (the fluid around a baby in the womb) or from tissue samples after delivery to create a reference guide. This guide will help doctors better diagnose rare genetic diseases that start before birth.
WHY IT MATTERSThis trial could improve how doctors diagnose rare genetic diseases in fetuses and newborns by establishing what normal DNA patterns look like before birth, which is currently unknown.

Researchers at a hospital in France are collecting biological samples (like blood) from 1,000 patients with rare nervous system diseases that may be caused by the immune system attacking the body. These samples will help scientists find new ways to diagnose and treat these diseases by identifying special markers in the blood that show disease activity.
WHY IT MATTERSIf you have a rare autoimmune neurological disease, participating in this sample collection could help researchers discover new biomarkers and treatments specifically for conditions like yours.

Researchers are studying how doctors treat a rare muscle weakness disease called generalized myasthenia gravis (gMG) in Russia. They want to understand what treatments work best in real-world practice by following 450 patients over time. This study is not testing a new drug, but rather collecting information about treatments that are already being used.
WHY IT MATTERSIf you have AChR-antibody positive generalized myasthenia gravis in Russia, this study could help doctors understand which current treatment approaches work best for patients like you in your region.

Boston Children's Hospital is looking for 10,000 families with rare genetic diseases that haven't been diagnosed or fully understood yet. Researchers will study the genes and proteins in these families to figure out what's causing their conditions. The goal is to help doctors diagnose and treat rare diseases better in the future.
WHY IT MATTERSIf your family has been searching for answers about a rare or undiagnosed genetic condition, this study could help identify what's causing it and contribute to better treatments for others with the same disease.

Researchers at the National Heart, Lung, and Blood Institute are collecting blood and tissue samples from up to 10,000 people to study rare genetic diseases. They want to understand what causes these diseases by examining the samples in a lab. People of any age with undiagnosed or heart and lung diseases can participate. Samples can be collected at the NIH Clinical Center or through your own doctor.
WHY IT MATTERSThis biorepository is actively recruiting and could help researchers identify the genetic causes of your undiagnosed condition, potentially leading to better treatments and diagnosis methods for rare diseases.

Researchers are looking for genetic causes of rare and unusual diseases in people living outside the United States who haven't had access to genetic testing. They're using new, powerful tools to study the DNA of about 400 people to find out what's causing their diseases. This study could help doctors understand and diagnose rare conditions that are hard to figure out.
WHY IT MATTERSThis trial focuses on underserved populations outside the US with limited access to genetic testing, potentially identifying new disease-causing genes that could lead to diagnoses for patients who have remained undiagnosed despite extensive medical evaluation.

Researchers at St. Jude Children's Research Hospital are recruiting 385 people—including patients, families, doctors, and scientists—to share their thoughts about ethical questions that come up when testing new treatments for rare brain and nerve diseases. The study wants to understand what different groups of people think is fair and right when designing these small, personalized treatment trials.
WHY IT MATTERSThis study directly shapes how future rare neurological disease trials will be designed and conducted, meaning your input as a patient or caregiver could influence the ethical standards that protect you in future treatment studies.
