An inherited neuromuscular disorder defined by numerous centrally placed nuclei on muscle biopsy and clinical features of a congenital myopathy.
Features include always present findings: Proximal upper limb amyotrophy, Distal muscle weakness, Generalized hypotonia, and Muscle fibrillation and others; and very common findings: Centrally nucleated skeletal muscle fibers, Areflexia, and Ptosis. 31 total HPO annotations.
Organ System | Phenotype Count | Example Features |
|---|---|---|
Muscles | 16 | Achilles tendon contracture, Flexion contracture, Distal muscle weakness |
Bones and joints | 4 | Excessive inward curve of the lower back (lumbar hyperlordosis), Excessive inward curvature of the lower spine (hyperlordosis), Centrally nucleated skeletal muscle fibers |
Head and neck | 3 | Facial palsy, Sleepy facial expression, Weakness of facial musculature |
Arms and legs | 3 | Proximal upper limb amyotrophy, Proximal upper limb muscle weakness, Distal lower limb muscle weakness |
Lab test results | 2 | Elevated creatine kinase (muscle enzyme) (elevated circulating creatine kinase concentration), Mildly elevated creatine kinase |
Eyes | 1 | Ptosis |
DNM2 encodes dynamin 2 (870 aa). Catalyzes the hydrolysis of GTP and utilizes this energy to mediate vesicle scission at plasma membrane during endocytosis and filament remodeling at many actin structures during organization of the actin cytoskeleton. Highest expression in Lung (107.7 TPM) and Skin Sun Exposed Lower leg (97.2 TPM).
Autosomal dominant centronuclear myopathy is caused by mutations in the DNM2 gene on chromosome 19.
DNM2 is classified as a druggable target (Clinically Actionable, Enzyme, and Transporter categories) with score 4.4.
Genetic testing for DNM2 is available. Testing is considered confirmatory for diagnosis.
Phenotype severity distribution: 10 always present features, 3 very common features, 7 common features.
Estimated prevalence: Unknown (Unknown prevalence).
No clinical trials have been registered for autosomal dominant centronuclear myopathy.
9 publications have been identified in PubMed for autosomal dominant centronuclear myopathy. Research spans Basic Science / Preclinical (33%), Case Report / Case Series (22%), and Review / Meta-Analysis (11%).
