Charcot-Marie-Tooth disease, type 4H (CMT4H) is a demyelinating CMT peripheral sensorimotor polyneuropathy. It has been described in 10 individuals from two large consanguineous families from Lebanon and Algeria. Onset occurs within the first two years of life with slowly progressive muscle weakness in the distal extremities. Other common features include delayed walking, an abnormal gait, scoliosis and pes equines with toe retraction. CMT4H is caused by mutations in the FGD4 gene (12p11.1). Transmitted in an autosomal recessive manner. [from SNOMEDCT_US]
