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

  • Should the main types be separate primary entries?
  • How should neurology and genetics sources be linked?
  • The registry entry has merged aliases naming subtypes and syndromes; should they be split off?
