Dejerine-Scottas syndrome

Genetic peripheral nerves neuropathy causing/carachterising/resulting/in which loss of sensation, motor function and muscle waist

Onset – early childhood – extremities

Onset occurs in infancy or early childhood, usually before 3 years of age. Progression is slow until the teenage years at which point it may accelerate, resulting in severe disability.

Symptoms are usually more severe and rapidly progressive than in the other more common Charcot–Marie–Tooth diseases. Some patients may never walk and solely use wheelchairs by the end of their first decade, while others may need only a cane (walking stick) or similar support through life.
