In brief
At just 22 years old, Prince Frederik succumbed to a rare genetic mitochondrial disorder while dedicating his efforts to support others facing similar challenges.
Prince Frederik of Luxembourg, a passionate advocate for genetic disease awareness, has passed away at the age of 22 after battling POLG, a rare genetic condition affecting mitochondrial function. His father, Prince Robert, shared the heartbreaking news of his son's death on March 1, following a protracted illness that began with a discovery at age 14—a harmful mutation in the POLG gene integral to DNA replication and repair. POLG disease is estimated to affect one in 10,000 individuals and manifests through multiple organ failures and debilitating symptoms like seizures. “It’s akin to a battery that never recharges, diminishing over time,” remarked Prince Robert, reflecting on the disease’s nature. Renowned expert in mitochondrial disorders, Sir Doug Turnbull, noted that POLG's relentless progression severely compromises health across numerous systems.As a founder and creative director of the POLG Foundation, Prince Frederik utilized his own genetic information for research initiatives, contributed to informative films, and developed a clothing line to fund further studies aimed at understanding the condition. The organization is known for promoting awareness and support for those afflicted with similar genetic challenges.Born in Aix-en-Provence and raised in Switzerland, Prince Frederik was notably fond of the television series “The Office,” having watched it multiple times. During his final hospitalization, grappling with pneumonia and severe infections, he found solace in observing the Eiffel Tower and asked his brother, Alexander, to capture the sunset outside his window.Frederik's passing occurs just months before his cousin, Prince Guillaume, is expected to ascend the throne of Luxembourg, following the retirement of Grand Duke Henri. Reflecting on his journey with POLG, Frederik remarked in a documentary made by his foundation, “As a child, one has dreams and aspirations, yet the reality of living with POLG quietly narrows your world.” His legacy and unwavering commitment to advocacy will continue to inspire many in the fight against genetic disorders.
