Charcot–Marie–Tooth disease
Let an agent explain Charcot-Marie-Tooth disease and its classification in neutral clinical terms, relay genetics, diagnosis and management in general from neurology and genetics sources, describe support and research, and route people with symptoms or diagnoses to neurologists and genetic counsellors.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain Charcot-Marie-Tooth disease and its classification in neutral clinical terms, relay genetics, diagnosis and management in general from neurology and genetics sources, describe support and research, and route people with symptoms or diagnoses to neurologists and genetic counsellors.
A group of inherited disorders of the peripheral nerves, also called hereditary motor and sensory neuropathy, that cause progressive weakness and wasting of the muscles of the feet, legs and hands, foot deformities and sensory loss, classified into demyelinating type 1 including subtypes such as 1E, axonal type 2, the severe early-onset type 3 or Dejerine-Sottas disease, intermediate types, X-linked forms and rare syndromic forms including autosomal recessive axonal neuropathies and neuropathy with optic atrophy; it is caused by mutations in more than 100 genes and managed by supportive care, therapy and orthotics.
What it is for: Not applicable; a disease group.
It can be explain classification and genetics; relay diagnosis and management; describe support and research; route to specialists.
Distinguishing features
Inherited
Peripheral nerve degeneration
Distal weakness and sensory loss
Genetically heterogeneous
What it looks like
Not a visible object; foot deformities and muscle wasting in affected people.
Physical character
prevalence: about 1 in 2500 people
genes involved: over 100 count
most common cause: PMP22 duplication note - type 1A
How it is recognised
Inherited peripheral neuropathy
Type 1 including 1E, type 2, type 3, X-linked, autosomal recessive axonal and syndromic forms with optic atrophy
Acquired neuropathies such as diabetic neuropathy are not inherited; muscular dystrophies affect muscle directly

What the second pass must settle

- How should neurology and genetics sources be linked?
- The registry entry has merged aliases naming subtypes and syndromes; should they be split off?
