Charcot-Marie-Tooth disease type 4B2
MONDO:0011475Charcot-Marie-Tooth disease type 4B2 (CMT4B2) is a subtype of Charcot-Marie-Tooth type 4 characterized by a severe, early childhood-onset of demyelinating sensorimotor neuropathy, early-onset glaucoma, focally folded myelin sheaths in the peripheral nerves, severely reduced nerve conduction velocities, and the typical CMT phenotype (i.e. distal muscle weakness and atrophy, sensory loss, and frequent pes cavus). Severe visual impairment leading to visual loss has also been reported.
Also known as: CMT4B2, Charcot-Marie-Tooth disease type 4 caused by mutation in SBF2, Charcot-Marie-Tooth disease type 4B2, SBF2 Charcot-Marie-Tooth disease type 4, CMT 4B2, Charcot Marie Tooth disease type 4B2, Charcot-Marie-Tooth disease, type 4B2, Charcot-Marie-Tooth disease, type 4B2, with early-onset glaucoma

New study aims to unravel nerve mysteries in rare diseases
Knowledge-focused Recruiting nowThis study looks at how nerves work in people with Charcot-Marie-Tooth disease and other nerve disorders like CIDP. Researchers will use special electrical tests and ultrasound to measure nerve and muscle changes. The goal is to better understand these conditions, not to test a n…
