Living with Charcot-Marie-Tooth disease type 4E
An inherited nerve condition present from early infancy with low muscle tone and very slow nerve signals.
Understanding Charcot-Marie-Tooth disease type 4E
It looks like Dejerine-Sottas syndrome, with low muscle tone or delayed motor skills in infancy and extremely slow nerve signals. Breathing problems and cranial nerve involvement are possible. Typical features are weakness and wasting in the muscles farthest from the center of the body, loss of feeling, and foot differences.

Quick facts
Changes in the EGR2 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.
