As Rare Disease Month comes to a close and Rare Disease Day approaches, we are turning our focus beyond the United States to explore what rare disease care looks like in Brazil, and how genomics is reshaping the diagnostic journey.

In this episode, we take a deep dive into the rare disease landscape in Brazil, including how patients access genetic testing within a public healthcare system, the barriers families face compared to those in the U.S., and how whole genome sequencing (WGS) is accelerating diagnoses that once took years or even decades.

Joining us is Dr. João Bosco de Oliveira Filho, a physician-scientist who helped lead Brazil’s national rare disease genomics initiative, Genomas Raros, and now continues this work through his laboratory, NeoGenomica. We’re also joined by Victor Camillo from MGI, who shares a global technology perspective on how large-scale sequencing efforts can expand access to rare disease diagnostics, especially in middle-income countries.

Together, we discuss:

How rare disease care in Brazil compares to the U.S.
Why whole genome sequencing is a game changer for undiagnosed patients
Lessons learned from national-scale genomics initiatives
The role of public–private partnerships in sustaining innovation
What the future holds for rare disease diagnostics worldwide
