Dejerine–Sottas disease, also known as, Dejerine–Sottas syndrome,

peripheral nerves, demyelination, and resulting progressive muscle wasting and somatosensory loss. The condition is caused by mutations in various genes and currently has no known cure.[2]

The disorder is named for Joseph Jules Dejerine and Jules Sottas, French neurologists who first described it.[4][5]

Signs and symptoms

Onset occurs in infancy or early childhood, usually before three years of age. Progression is slow until the teenage years at which point it may accelerate, resulting in severe disability.[1]

Symptoms are more severe and rapidly progressive than in the other more common Charcot–Marie–Tooth diseases. Some patients may never walk and will be reliant on wheelchair use by the end of their first decade, while others may need only a cane, crutches, or similar support through most of their lives, but this is rare.[1]

Dejerine–Sottas disease is characterized by moderate to severe lower and upper extremity

areflexia, and slow acquisition of motor skills in childhood. Symptoms that are less common can include limitation of eye movements, other eye problems such as nystagmus or anisocoria, or moderate to severe hearing loss.[2]

Causes

Dejerine–Sottas neuropathy is caused by a genetic defect either in the proteins found in

autosomal recessive manner.[2]

Diagnosis

On medical imaging, the nerves of the extremities (and cranial nerves in some cases) appear enlarged due to hypertrophy of the connective interstitial tissue, giving the nerves a distinct "onion-bulb" appearance. Peripheral (and possibly cranial) nerve excitability and conduction speed are reduced.[1]

Treatment

Management is symptomatic for this condition.[10]
