What it is
A rare genetic disease characterized by juvenile-onset insulin-dependent diabetes mellitus associated with central and peripheral nervous system abnormalities with variable onset between infancy and adolescence. Neurological manifestations include combined cerebellar and afferent ataxia, sensorineural hearing loss, pyramidal tract signs, and demyelinating sensorimotor peripheral neuropathy. Hypothyroidism has been reported in some patients. Brain imaging may show generalized cerebral atrophy.

ICD-10 codes
ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
