Autosomal dominant Charcot-Marie-Tooth disease type 2W

What it is

A rare predominantly axonal hereditary motor and sensory neuropathy characterized by a broad phenotypic spectrum of slowly progressive signs and symptoms mainly affecting the lower limbs. Most patients present with gait difficulties and distal sensory impairment, while some may lack sensory symptoms altogether. Pes cavus is frequently reported. Age of onset is also highly variable, ranging from childhood to late adulthood.

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.

Signs and symptoms

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.

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.
