Symptoms of CCDC78 Gene Centronuclear Myopathy Type 4 Genetic Test

Centronuclear myopathy (CNM) type 4, associated with mutations in the CCDC78 gene, is a rare genetic disorder that affects muscle function. This condition is characterized by muscle weakness (myopathy) that can vary in severity and distribution, often worsening over time. Recognizing the symptoms early can be crucial for management and treatment. DNA Labs UAE offers a comprehensive genetic test for CCDC78 gene mutations, enabling accurate diagnosis and facilitating proper care and interventions.

Understanding Centronuclear Myopathy Type 4

Centronuclear myopathies are a group of conditions that affect the structure of muscle cells, causing them to appear centrally nucleated under a microscope. Type 4 CNM, specifically caused by mutations in the CCDC78 gene, is a form that presents unique challenges and symptoms for those affected. The condition is inherited in an autosomal dominant manner, meaning a mutation in just one of the two copies of the gene can cause the disorder.

Key Symptoms of CCDC78-Related CNM

  • Muscle Weakness: One of the primary symptoms of CNM type 4 is muscle weakness, which can start in infancy, childhood, or even adulthood. This weakness may initially affect the muscles close to the center of the body, such as the hips and shoulders, and can progress to involve other muscle groups.
  • Delayed Motor Milestones: Children with this condition may experience delays in reaching developmental milestones related to movement, such as sitting up, crawling, or walking.
  • Facial Muscle Involvement: Some individuals may exhibit weakness in the muscles of the face, affecting facial expressions and possibly leading to difficulties with feeding and swallowing.
  • Respiratory Issues: Weakness in the muscles involved in breathing can lead to respiratory difficulties, which may require medical intervention in severe cases.
  • Ophthalmoplegia: A condition characterized by weakness or paralysis of the eye muscles, leading to difficulties with eye movement and sometimes resulting in drooping eyelids (ptosis).

Genetic Testing for CCDC78 Gene Mutations

Genetic testing for CNM type 4 involves analyzing the CCDC78 gene for specific mutations known to cause the condition. DNA Labs UAE offers a CCDC78 gene centronuclear myopathy type 4 genetic test that can provide definitive diagnosis for affected individuals or carriers of the mutation. This test is crucial for families seeking answers about their genetic health and for planning future family members.

Test Cost and Procedure

The cost of the CCDC78 gene centronuclear myopathy type 4 genetic test at DNA Labs UAE is 4400 AED. The test involves a simple blood draw or cheek swab from the patient. The sample is then analyzed in our state-of-the-art laboratory, where our team of experts looks for the specific mutations in the CCDC78 gene that are known to cause CNM type 4. Results are typically available within a few weeks and are thoroughly explained by our genetic counselors, ensuring that patients and their families understand the implications and next steps.


Understanding the symptoms of CCDC78-related centronuclear myopathy type 4 is crucial for early diagnosis and management. DNA Labs UAE is committed to providing accurate genetic testing to help diagnose this rare condition. With a comprehensive genetic test available, individuals and families can gain valuable insights into their genetic health, enabling informed decisions and appropriate interventions. If you suspect you or a family member may have symptoms of CNM type 4, consider reaching out to DNA Labs UAE for consultation and testing.
