At 18, Lucia Adarve had a complex medical history, having been diagnosed with multiple conditions, including epilepsy, lupus, and ADHD, without a clear understanding of her underlying issues. Struggling with milestones and experiencing seizures, Lucia was homeschooled by her mother, Lisa, who sought alternative methods to support her development. In 2025, after a comprehensive evaluation at Cincinnati Children’s Hospital, they were referred to the Cleveland Clinic’s Undiagnosed Disease Clinic. There, genetic testing revealed a mutation on Lucia’s PPP2R5D gene, diagnosing her with Jordan syndrome, a rare neurodevelopmental disorder affecting fewer than 500 individuals worldwide. This diagnosis provided relief for Lisa, affirming her concerns about Lucia’s health and experiences.
Why It Matters
Lucia’s case underscores the challenges faced by patients with rare medical conditions, often experiencing lengthy diagnostic journeys. Historically, patients with ultra-rare disorders can take more than a decade to receive accurate diagnoses, highlighting a gap in effective medical assessment and support. Advances in genetic testing, such as whole genome sequencing, are becoming crucial tools in identifying these complex conditions. Understanding rare disorders like Jordan syndrome can lead to better-targeted interventions and improve the quality of life for affected individuals.
