Common questions about Charcot-Marie-Tooth disease, axonal, with vocal cord paresis, autosomal recessive
Organ System | Phenotype Count | Example Features |
|---|---|---|
Muscles | 4 | Flexion contracture, Distal muscle weakness, Proximal lower limb muscle weakness |
Arms and legs | 2 | Proximal lower limb muscle weakness, Proximal upper limb muscle weakness |

GDAP1 encodes ganglioside induced differentiation associated protein 1 (358 aa). Regulates the mitochondrial network by promoting mitochondrial fission Highest expression in Brain Cerebellar Hemisphere (80.1 TPM) and Brain Frontal Cortex BA9 (56.7 TPM).
Charcot-Marie-Tooth disease, axonal, with vocal cord paresis, autosomal recessive is associated with mutations in the GDAP1 gene on chromosome 8.
The GDAP1 protein participates in Class I Peroxisomal Membrane Proteins pathway.
GDAP1 is classified as a druggable target with score 0.0.
Genetic testing for GDAP1 is available. Testing is considered confirmatory for diagnosis.
Phenotype severity distribution: 7 always present features, 4 common features.
1 clinical trial registered, 1 recruiting. Interventions under study include other interventions. Research is primarily sponsored by academic and government institutions.
