Charcot-Marie-Tooth disease

Inheritance patterns and prenatal diagnosis

Inheritance patterns

  • Autosomal dominant is the most common pattern of inheritance.
  • Autosomal recessive (least common)
  • X-linked passed to both sons and daughters. However, affected sons will usually display more severe symptoms.

Prenatal diagnosis
In families who have Type 1a prenatal diagnosis is now becoming available but is rarely requested.
