3303766014	Charcot-Marie-Tooth disease, type 4B1 (CMT4B1) is a severe early-onset demyelinating CMT peripheral sensorimotor polyneuropathy. It was initially described in an Italian family and around 10 additional families have been described so far. Onset occurs during early childhood with distal and proximal muscular weakness starting in the lower extremities, sensory loss and cranial nerve involvement. Foot deformities are frequent and diaphragmatic and facial involvement has been reported. CMT4B1 is caused by mutations in the gene encoding myotubularin-related protein 2 (MTMR2; 11q22), involved in polyphosphoinositide signaling. Transmitted in an autosomal recessive manner.	en	Definition	Active	Entire term case sensitive (core metadata concept)	SNOMED CT core
