Which are the symptoms of Central Core Disease?

Central Core Disease is a rare congenital myopathy primarily characterized by muscle weakness, hypotonia (low muscle tone), and a heightened risk of malignant hyperthermia when exposed to certain anesthesia. Symptoms typically manifest in infancy or early childhood, though the clinical presentation varies significantly between individuals, even within the same family.

What are the primary symptoms of Central Core Disease?

The hallmark of Central Core Disease is proximal muscle weakness, which most often affects the muscles around the hips and shoulders. Patients frequently report difficulty climbing stairs, running, or standing from a seated position. Because Central Core Disease is a disorder of the skeletal muscle, other common clinical features include:

• Generalized hypotonia (the "floppy baby" syndrome) observed during infancy.


• Delayed motor milestones, such as walking later than peers.


• Skeletal abnormalities, including scoliosis, hip dislocation, and foot deformities like pes cavus.


• Mild to moderate muscle weakness that remains relatively stable over time.

How does Central Core Disease affect quality of life?

While the muscle weakness in Central Core Disease is often non-progressive or very slowly progressive, it significantly impacts daily physical endurance. Fatigue is a common complaint among our 89 community members at DiseaseMaps.org. Because Central Core Disease can lead to orthopedic complications like scoliosis, many patients require physical therapy or assistive devices to maintain mobility and comfort in their daily lives.

When should families seek immediate medical attention?

The most critical clinical risk for those with Central Core Disease is malignant hyperthermia. This is a severe, life-threatening reaction to certain volatile anesthetic gases and the muscle relaxant succinylcholine. Patients and their families must ensure that all surgical teams are aware of the diagnosis of Central Core Disease before any procedure. Seek emergency care immediately if a patient exhibits unexplained high fever, rigid muscles, or rapid heart rate during or shortly after anesthesia.

How does the condition progress?

Unlike many other neuromuscular disorders, Central Core Disease is generally considered stable. Most individuals do not experience rapid loss of function. However, as patients age, they may notice increased joint stiffness or the secondary effects of long-term orthopedic issues. Regular monitoring by a neurologist and orthopedist is essential to manage the specific symptoms of Central Core Disease as they evolve throughout the lifespan.

Next steps

• Consult a neuromuscular specialist or a geneticist to discuss your specific variant.


• Always carry a medical alert bracelet indicating your risk for malignant hyperthermia.


• Join the community at DiseaseMaps.org to connect with others sharing their experiences with Central Core Disease.


• Engage in regular physical therapy to maintain muscle strength and joint flexibility.
