Living with Charcot-Marie-Tooth disease type 4D
An inherited nerve condition starting in childhood with severe nerve damage, foot differences, and hearing loss.
Understanding Charcot-Marie-Tooth disease type 4D
Weakness and wasting happen in the muscles farthest from the center of the body, along with foot differences and very slow nerve signals. Hearing loss from nerve damage usually leads to deafness in the third decade. Tongue wasting has also been reported.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Weakness in the lower legs
- Wasting of leg muscles
- Hearing loss from nerve damage
- Foot differences
- Delayed motor skills
- Unsteady walking
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
Diagnosis
- 1Talk with your doctor
Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.
- 2See a specialist
Specialists who may be involved include brain and nervous system specialists and genetic specialists.
- 3Consider genetic testing
Changes in NDRG1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

Quick facts
Changes in the NDRG1 gene cause this condition. It is inherited in an autosomal recessive way, so a child inherits a changed copy of the gene from each parent.
