Achondrogenesis



Achondrogenesis

Definition

Achondrogenesis is a defect in the development of bone and cartilage. It is thought to be inherited.

Causes

Achondrogenesis is a rare type of dwarfism

Symptoms

  • very short trunk, arms, legs and neck
  • head appears large in relation to the trunk
  • small lower jaw
  • narrow chest

Exams and Tests

X-rays show characteristic bone abnormalities.

Treatment

No treatment is available. Genetic counseling may be appropriate.

Outlook (Prognosis)

The outcome is generally very poor. Many infants with achondrogenesis are stillborn or die shortly after birth because of breathing problems related to the abnormally small chest.

This condition is often fatal early in life.
