Rare Disease Day
A Rare Public Health Challenge
Posted on by Joni Rutter, Ph.D., National Center for Advancing Translational Sciences
Most public health challenges may seem obvious. The COVID-19 pandemic, for example, swept the globe and in some way touched the lives of everyone. But not all public health challenges are as readily apparent.
Rare diseases are a case in point. While individually each disease is rare, collectively rare diseases are common: More than 10,000 rare diseases affect nearly 400 million people worldwide. In the United States, the prevalence of rare diseases (over 30 million people) rivals or exceeds that of common diseases such as diabetes (37.3 million people), Alzheimer’s disease (6.5 million people), and heart failure (6.2 million people).
Shouldering the Burden of Rare Diseases
As with common diseases, the personal and economic burdens of rare diseases are immense. People who live with rare diseases often struggle for years before they receive an accurate diagnosis, with some remaining undiagnosed for a decade or longer. The diagnostic odyssey includes countless doctor visits, unnecessary tests and procedures, and wrong diagnoses. For people in rural and low-income communities, lack of access to care is an additional barrier to an accurate diagnosis. And a diagnosis often doesn’t lead to better health—only about 5 percent of rare diseases have U.S. Food and Drug Administration–approved treatments.
Collectively, the personal burdens of those with rare diseases impose a significant economic cost on the nation. When quantifying the health care expenses for people with rare diseases, we found that they have three to five times greater costs than those without rare diseases [1]. In the United States, the total direct medical costs for those with rare diseases is approximately $400 billion annually, a figure validated independently by the EveryLife Foundation for Rare Diseases. The EveryLife study also included indirect and non-medical costs, resulting in a higher total economic burden of nearly $1 trillion annually [2].
What’s even starker is that the true scope and impact of rare diseases actually may be greater because rare diseases aren’t easily visible in our health care system. Many of the diseases are too rare to have a code that identifies them in the electronic health record (EHR).
Speeding Up the Search for Solutions
Each and every day, NIH’s National Center for Advancing Translational Sciences (NCATS) works with patients, advocates, clinicians, and researchers to meet the public health challenge of rare diseases. Driving those conversations are three overarching goals to help people living with rare diseases get the high-quality care they need, faster:
1. Shorten the duration of the diagnostic odyssey by more than half. The diagnostic odyssey for someone with a rare disease takes on average seven years, and there are several ways we can speed the journey. For example, we are designing computational tools to detect rare genetic disorders from EHR data. This work is part of a broader research effort focused on using genetic analysis and machine learning to make it easier for health care providers to diagnose people with rare diseases correctly. Also, connecting patients more quickly with each other and the research community can hasten the search for answers. Check out the resources below to learn about rare diseases, find patient support organizations, and get involved in research efforts.
2. Develop treatments for more than one rare disease at a time. A key strategy is leveraging what rare diseases have in common. Some of our efforts build upon the fact that 80–85 percent of rare diseases are genetic. We can use this knowledge to develop genetic and molecular interventions for groups of rare diseases. Two programs—the Platform Vector Gene Therapy pilot project and the Bespoke Gene Therapy Consortium, which is part of the public-private Accelerating Medicines Partnership®—are streamlining the gene therapy development process. Their ultimate goal is to make gene therapies more accessible to many people with rare diseases. We also have joined in to advance the clinical application of genome editing for rare genetic diseases.
The NCATS-led Rare Diseases Clinical Research Network, which is supported across NIH, brings scientists together with rare disease organizations and patient advocacy groups to better understand common characteristics, which also might speed clinical research. With this in mind, we are adapting a clinical trial strategy used in cancer research to test a single therapy on multiple rare diseases.
3. Make it easier and more efficient for scientists to discover and develop treatments for rare diseases. NCATS develops ways for new treatments to reach people more quickly. Repurposing drugs, for example, is revealing already-approved drugs that may work for rare diseases. Programs such as Therapeutics for Rare and Neglected Diseases and Bridging Interventional Development Gaps move basic research discoveries in the lab closer to becoming new drugs. Ambitious initiatives, such as the Biomedical Data Translator, unite data from biomedical research, clinical trials, and EHRs to find treatments for rare diseases faster.
The COVID-19 pandemic showed us the power of working together to solve public health challenges. Let’s now come together to address the public health challenge of rare diseases. If you want to get involved, please join us at Rare Disease Day at NIH 2023 on February 28. You’ll hear personal stories, learn about the latest research, and discover helpful resources. I hope to see you there!

Seven Questions for a Rare Disease Warrior

Tomorrow is Rare Disease Day at NIH, marking the 12th year that this annual event has been held on the NIH campus. Similar gatherings have been organized independently around the world this week, all to raise awareness for the nearly 7,000 rare diseases, some affecting just a few dozen people. But, collectively, rare diseases are hardly rare. One in 10 Americans has a rare disease (defined as affecting 200,000 or fewer individuals in the US), and about half are children. Without needed treatments, about 30 percent of these children will die by age 5.
To join everyone in raising awareness, I wanted to feature on my blog a unique perspective about rare diseases, and David Fajgenbaum certainly has one. Fajgenbaum is an immunologist and NIH grantee at the Perelman School of Medicine, University of Pennsylvania, Philadelphia. When Fajgenbaum isn’t running studies or clinical trials, he must remain vigilant of his own health. Fajgenbaum has a rare disease called idiopathic multicentric Castleman disease (iMCD), and this devastating condition, which emerged while he was in medical school, nearly claimed his life several times.
Now 34 years old and in a long remission, Fajgenbaum can discuss rare diseases as a doctor, as a patient, as a researcher, and as an advocate. His personal journey, published in his recent book Chasing My Cure, is a gripping read. Fajgenbaum was kind enough to answer a few of my questions on rare diseases and share some of his lessons learned.
The last time that I saw you, David, you looked great. How long have you been in remission?
I have been in remission for 73.83 months. I say 73.83, because I know that I can’t round up—I may relapse tomorrow. But I also refuse to round down because so many colleagues and I have worked so hard for every day of remission for me and other patients with my disease.
For me, every day is particularly special, because I never thought that I would be alive this long. As you know, I became deathly ill during medical school in 2010 and even had my last rites read to me when my doctors didn’t think I would survive. I was eventually diagnosed with idiopathic multicentric Castleman disease (iMCD), which is like a deadly cross between cancer and autoimmunity. Chemotherapy saved my life, but I would go on to have four near-death relapses.
After one of those relapses, I got out of the hospital and dedicated my life to conducting iMCD research and co-founded the Castleman Disease Collaborative Network (CDCN). Later, I identified a particular cellular pathway called mTOR that was highly active in my samples. I began testing on myself an mTOR inhibitor [sirolimus]—developed 30 years before and approved for kidney transplantation but never considered for iMCD. It’s this drug that has kept me in remission for the last 73.83 months and helped other people. During this time, I’ve been able to marry my wife, have a daughter, help launch a new center at Penn specializing in rare diseases, and write a book to share my personal journey with others.
As a physician-scientist and as a person with a rare disease, what have you learned about the biomedical research process?
I’ve learned so much, but I’d like to highlight three lessons in particular. First, we must leverage all perspectives to prioritize research and give us the best chance of translating research into meaningful breakthroughs. The traditional approach to rare disease research involves a subset of researchers within a rare disease field submitting their best ideas for funding and a panel selecting the best applicant.
Through the CDCN, we’ve spearheaded a new approach called the Collaborative Network Approach, where we crowdsource research questions from the entire community of patients, physicians, and researchers (not just a subset of researchers) and then recruit the best researchers in the world (not just from within the Castleman disease field) to perform the prioritized studies. We’re now working to improve and spread this approach to other diseases.
Second, collaboration between all players is critical. Patient advocacy groups are uniquely positioned to serve as the glue between all stakeholders. Researchers and physicians need to share ideas, data, and samples with one another. Patients need to be actively involved in research question prioritization and study design. Biopharma and the Food and Drug Administration (FDA) need to be engaged early in the process of research discoveries and drug development.
Third, we must leverage all 1,500-plus, existing FDA-approved drugs to help as many patients without any options as quickly as possible. As you know, less than 5 percent of the nearly 7,000 rare diseases have an FDA-approved therapy, but many diseases share similar cellular and genetic defects that could make them susceptible to the same drugs. I’m literally alive today thanks to a drug developed for another disease. How many of the drugs approved for one disease may be effective for many of the 7,000 diseases without any? I don’t know the answer, but I hope we can begin to address this important question and incentivize repurposing.
In your experience, how can people with rare diseases help to advance progress for their conditions?
There is so much work to be done for so many rare diseases. Sometimes it can feel so overwhelming and like “what can I really do?”
But I’ve learned that there are so many ways that we can each contribute and so many incredible examples of advocates who have made a difference for themselves and those that they love. Cystic fibrosis and chordoma are just two of many examples where patient-advocates have been critical partners in transforming their diseases.
People with rare diseases can raise funds for research. Every dollar truly counts. We can work with existing organizations for our disease to ensure that those funds are distributed as efficiently and effectively as possible. If there are major gaps within our rare disease fields that aren’t being addressed by existing organizations, we can start new rare disease organizations (but we should try to avoid this whenever possible). We can contribute samples and data towards research, participate in clinical trials, and share with other patients about our experiences. We can advocate for new drug development and repurposing already-FDA approved drugs for our diseases.
What would you tell other researchers who are studying rare diseases?
I would tell other rare disease researchers that you are doing such important work. You give us hope that a treatment can be identified that will change our lives. It’s an incredible responsibility and incredibly stressful. There are unfortunately far too many scientific questions and diseases with major unmet need for any of us to compete over the use of samples and data. We have to share these within our fields. And we must also work together across rare diseases. We can’t continue to reinvent the wheel; we must share learnings with one another
I enjoyed doing the CastleMan Warrior Flex with you. Tell us more about what it represents?
Doing the CastleMan Warrior Flex with you is one of my favorite pictures. In fact, it’s hanging up in my office.
Castleman disease was named after Dr. Benjamin Castleman, who first described our disease in 1954. We have repurposed the “Castleman” name to be a “CastleMan Warrior” (below is our cartoon mascot). We do the “CastleMan Warrior” Flex to raise awareness for Castleman disease and rare diseases generally—we’re all warriors in the rare disease space.
What are your future plans as a rare disease advocate and as a researcher?
We’ve made a lot of progress for Castleman disease: we’ve advanced our findings about mTOR towards a clinical trial, gained approval for the treatment siltuximab for iMCD, developed diagnostic criteria and treatment guidelines, and invested about $1.5 million into Castleman disease research, which has led to over $7 million in additional funding from other sources.
But we still have important work ahead of us. The treatments sirolimus and siltuximab work for only a portion of all iMCD patients. We need to identify more effective treatments for all forms of Castleman disease.
I will continue to study Castleman disease and other diseases at the intersection of autoimmunity and oncology to gain insights into how the immune system works in myriad diseases. In parallel, I will continue to advocate for the adoption of the “Collaborative Network Approach” to crowdsource all stakeholder perspectives as well as for new models for drug repurposing.
Any other issues that you’d like to address?
I feel a responsibility to share with the world the lessons that I’ve learned about life from nearly dying five times. This is a major reason that I wrote my book.
One lesson that I think about a lot is related to my growing up playing football. Some of my games were extended into an overtime period to decide the outcome. In overtime, every second counts and you’re totally focused on what’s important. I’ve lived with that exact same feeling ever since I had my last rites read to me.
I’ve also learned that humor can be incredibly powerful. You may think that a good laugh may be the last thing that you’d want to do when you’re dying in the ICU. But laughing with the people that I love actually helped me feel like I could transcend my illness, and it helped to connect us.
My greatest regrets on my deathbed were not things that I had done or said. I regretted what I didn’t do or didn’t say and that I would no longer be able to do. I now follow the motto: “Think It, Do It.” In other words, we should reflect on what we’re hoping for and then turn our hopes into action.
Finally, I’ve learned that it really takes a strong team to make a difference in the world, especially against diseases. If it was just me on my own, we would have made less than 1 percent of the progress that’s been achieved. I hope that all rare disease warriors will join together into strong teams, armies even, and make a difference in the world.

Thoughts from the Front Lines of Rare Disease Research
Posted on by Dr. Francis Collins
There are nearly 7,000 rare diseases, some of which affect just a few dozen people. Yet, if one considers all these conditions together, about 30 million people in the United States have rare diseases. On this Rare Disease Day, I’d like to challenge each of you to think about how we can raise the visibility of individuals living with rare diseases, as well as the researchers working hard to help them.
I’d like to introduce you to Harper Spero, who is using her rare gift of storytelling to share the experiences of people with a wide variety of conditions that she likes to call “invisible illnesses.” Through her podcast series, called Made Visible, this 34-year-old New York City native is among the many people helping to spread the word that rare diseases are not rare.
Spero knows what it’s like to live with a rare disease. Shortly after she was born, it became clear that she was unusually prone to infections. But doctors had a hard time figuring out what exactly was wrong with this little girl. Finally, at the age of 10, Spero was diagnosed with Hyper-Immunoglobulin E Syndrome (HIES), also known as Job’s syndrome. There currently is no cure for this rare genetic disease, which impairs the immune system and affects multiple parts of the body. But Spero is determined to live a normal life despite her chronic “invisible illness.”
Spero also knows what it’s like to take part in biomedical research. Seven years ago, she came to the NIH Clinical Center here in Bethesda, MD, seeking help for a large cyst in her right lung. It marked the beginning of a positive partnership with a Job’s syndrome research team led by two of NIH’s many dedicated physician-scientists, Alexandra Freeman and Steven Holland. Not only did the NIH researchers work with Spero to figure out the best ways of managing her symptoms, they are using what they’ve learned from her and about 175 other Job’s syndrome patients to develop approaches for earlier diagnosis and interventions. Spero, who visits the Clinical Center annually and communicates with the NIH team on a weekly basis, has been so inspired by the experience that she even chose to feature Dr. Freeman in one of her recent podcasts.
Unlike Spero, I don’t have a podcast—at least not yet. But I do have a blog, and Spero was kind enough to respond to a few of my questions on rare diseases and medical research. So, I’m sharing her thoughts below—I hope you are inspired by them as much as I was!
Why do you feel it is important for people with rare diseases to take part in medical research?
Without research, we can’t make any improvements, changes or find cures. Participating in medical research allows researchers and doctors to learn about the trends (or lack of) between patients, and determine what’s working and what’s not.
What have your own experiences been with the health-care system and medical research?
When I was younger, I really didn’t want to be a specimen. I was going through so much trying to find answers and treatments for myself that it was hard to think about how it would help other patients down the road to be sharing my experiences. I didn’t want to add another doctor’s visit to my schedule. After coming to NIH in 2012, I recognized the importance of being part of the research because it could essentially help me, other patients and for early detection of rare diseases. I recognize that the medical researchers are often much more compassionate than many doctors who simply treat symptoms. Researchers are curious and genuinely care to understand you and your story.
Your podcast is fantastic. How has it affected you to hear and share the stories of so many people affected by rare diseases?
I was definitely aware how many people were living with rare diseases, but I was surprised by how many people were willing to share their stories on my show and how many people wanted to listen to these stories. I hadn’t heard stories being shared in this way around this topic and I wanted to be the one who brought them to life. Many of my guests haven’t publicly (let alone with friends or family) shared their stories so I’m honored that they’re willing to do it with me. They see how important it is to have these conversations and to educate people on what it’s like to have an invisible illness.
What would you tell someone who’s just learned he or she has a rare disease?
You don’t have to do this alone! Find a team of medical professionals you trust to support you. I spent most of my life without a team of doctors that I loved and truly understood me, and now I can’t imagine my life without my team at NIH. Also, talk to your loved ones—let them know what you’re feeling and discuss how they can support you. This is likely new for them too and there’s no right way of navigating and managing a rare disease.
What would you tell a young person who’s considering becoming a rare disease researcher?
Thank you for your interest in doing this! We need more compassionate, curious and passionate people doing this work and investing their time to learn more and help find answers for rare diseases. Please treat us with respect and care.
If you could change one thing in the medical care/research of rare disease, what would it be? And what about in society in general?
There’s a way to do your job without treating patients like guinea pigs. We’re humans too, and we’re humans who have likely been through the wringer in the medical world. Be kind to us. Treat us the way you’d like to be treated. Compassion seems to be a word I’m using a lot. I think society can be more compassionate towards one another especially around rare disease. You can never fully understand what someone is going through so ask questions, show you care and treat people with kindness.
What are your hopes for the future?
I’d love there to be more answers and solutions for navigating a rare disease. A lot of the treatments I do are based on trial-and-error. What works for one patient definitely doesn’t always work for me. So, we’re constantly trying to navigate what works best for me. I’d love to see a cure to be found for Hyper IgE/Job’s Syndrome, as well as other rare diseases.
