Charcot-Marie-Tooth disease, demyelinating, type 1F
Charcot-Marie-Tooth disease, demyelinating, type 1F
An autosomal dominant form (OMIM:607734) of Charcot-Marie-Tooth disease characterised by an early (ages 1–13) onset of sensorineural hearing loss, segmental demyelination and remyelination with onion-bulb formation on nerve biopsy, slowly progressive distal muscle atrophy and weakness, absent deep tendon reflexes, and hollowed feet.Molecular pathology
Defects of NEFL, which encodes a light-chain neurofilament protein involved in maintaining neuronal calibre, cause Charcot-Marie-Tooth disease type 1F.
