About the Event

The 2026 Joint Rare Diseases Symposium, co-hosted by CHOC Research Institute, now part of Rady Children's Health and the University of California, Irvine (UCI), unites scientists, clinicians, and patient advocates in a shared mission to push the boundaries of what’s possible in rare disease research.

Together, we explore breakthroughs across neurology, genetics, metabolism, and beyond—showcasing innovations in clinical trials, novel therapeutics, and cutting-edge biomedical science. From gene and cell therapies to advanced imaging, biomarker discovery, and multiomic approaches, the symposium shines a light on the future of diagnosis and treatment.

But this gathering is more than science alone. It is a place to see the unseen—the patient journeys, the hidden challenges, and the quiet resilience that drive our work forward. Hearing directly from families affected by rare diseases reminds us that behind every discovery are lives waiting for hope, healing, and answers.

We look forward to seeing you at the following 2026 events:

Accreditation Information

CHOC is accredited by the California Medical Association (CMA) to provide continuing medical education for physicians. CHOC designates this live activity for a maximum of 2.75 AMA PRA Category 1 Credits™. Physicians should claim only the credit commensurate with the extent of their participation in the activity.

  • Wednesday, February 25, 2026: Rare Disease Grand Rounds (Virtual)
  • Friday, February 27, 2026: Rare Disease Scientific Program, Patient Presentations, Community Engagement, Poster Sessions, and Sponsor Exhibition (in-person at Beckman Center)

Evaluation

All participants will have 30 days from the end of the activity to complete an evaluation for each day and will be able to download their own certificate of credit or completion. Instructions will be emailed to all participants who signed in each day.

Nurses: The California Board of Registered Nursing recognizes the use of AMA PRA Category 1 Credit™ toward credit for contact hours. Report “AMA PRA Category 1 Credit™” or “Category 1” as the BRN Number.

The University of California’s and CHOC’s nondiscrimination policy includes protections for sex and gender identities. A key element of creating a safe space for people of all sexes and gender identities is the respectful use of gender pronouns. We strive to create an environment of equity and inclusion with opportunities for everyone to reach their potential.

Asking our community what their gender pronouns are and consistently using them correctly is one of the most basic ways to show respect for their gender identity. Discussing and correctly using gender pronouns sets a tone of allyship. It can truly make all the difference, especially for new rare researchers who may feel particularly vulnerable in a new environment.


Financial Disclosures

Community: Cure VCP Disease

Speaker: Brandon  Feldt

We hope that our presence at the symposium aims to provide patients and families with vital information about VCP disease, connect them to support resources and community, and help them participate in research that advances treatment development. By sharing our patient-centered model and collaborative approach, we hope to inspire and support the broader rare disease community in their own fights for treatments and cures.

Community: FamilieSCN2A Foundation

Speaker: Leah Myers 

We hope to share our foundation's story- how it started and how far we've come. We were recipients of CZI: Rare as One grant, which accelerated our growth within our community, within the rare disease community, with the scientific/medical community, and with industry partners. We advocate for genetic testing as changes in the SCN2A gene are considered to be a leading single-gene cause of autism spectrum disorder. Diagnosis leads to awareness which ultimately leads to a cure.

Community: Project Alive

Speaker: Darcy DenneenKristin  McKay

We aim to share insights from the Hunter Health program and highlight strategies to improve treatment access as new therapies emerge for Hunter syndrome. Our goal is to foster cross-institution collaboration that advances equitable care across the rare disease community.
