Hereditary sensory and autonomic neuropathy type 6

What it is

A rare hereditary sensory and autonomic neuropathy characterized by hypotonia in infancy, variable psychomotor retardation, markedly impaired pain sensitivity with poorly healing distal ulcerations and painless fractures leading to joint deformities and amputation of fingers and toes, altered deep tendon reflexes, and dysautonomic symptoms including hypohidrosis and heat intolerance, chronic diarrhea, pupillary abnormalities, or urinary incontinence. Sensorineural hearing loss has also been reported. The severity of the disease is highly variable, with severe cases being potentially lethal in infancy.

Disease

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.

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.

Reached through the ICD-10 categories this disease is filed under, so these describe the broader group rather than this disease specifically.
