Young adult-onset distal hereditary motor neuropathy

What it is

Young adult-onset distal hereditary motor neuropathy is a rare autosomal recessive distal hereditary motor neuropathy characterized by slowly progressive muscular weakness, hypotonia and atrophy of the lower limbs, more pronounced distally, leading to paralysis, and loss of tendon reflexes. Additional features may include pes cavus and mild dysphonia. The upper limbs are relatively spared.

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.

Related health topics

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