POLG Mitochondrial Disease

Prince Frederik of Luxembourg, aged 22, passed away on March 1, 2025, in Paris. His family delayed the announcement of his death, which was attributed to POLG mitochondrial disease. This rare genetic disorder impacted his life and health. Frederik was diagnosed at the age of 14 and became an advocate for awareness and research through the POLG Foundation, which he founded in 2022.

About POLG Mitochondrial Disease

POLG mitochondrial disease is a genetic disorder that affects the body’s ability to produce energy. It disrupts mitochondrial function, leading to multiple organ dysfunction. The disorder is caused by mutations in the POLG and POLG2 genes, which are essential for mitochondrial DNA replication. Over 200 mutations have been identified, complicating diagnosis and treatment.

Symptoms and Diagnosis Challenges

Symptoms of POLG disease vary widely. They can range from mild to severe, including muscle weakness, epilepsy, and liver failure. Diagnosis is often delayed due to the disease’s complexity. Many patients remain undiagnosed for extended periods, leading to late-stage identification of the condition. This lack of awareness extends to healthcare professionals, making early intervention difficult.

Treatment Options and Quality of Life

Currently, there is no cure for POLG mitochondrial disease. Treatment focuses on symptom management and improving quality of life. Patients may receive supportive care, including physical therapy and medications to manage specific symptoms. Ongoing research aims to discover effective therapies and potential cures.

The Role of Advocacy and Awareness

Prince Frederik’s advocacy work was very important in raising awareness about POLG disease. Through the POLG Foundation, he aimed to educate the public and medical community about the disorder. His efforts brought into light the need for better diagnostic tools and treatment options, as well as support for affected families. Frederik’s legacy continues to inspire ongoing research and advocacy in the field of mitochondrial diseases.

The Impact of Mitochondrial Disorders Globally

Mitochondrial disorders, including POLG disease, affect millions worldwide. They often go unrecognised, leading to challenges in diagnosis and treatment. Increased awareness and research are crucial for improving patient outcomes. Advocacy groups play a vital role in supporting affected individuals and families, pushing for advancements in medical research and healthcare policies.
