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. It is usually fatal at birth or soon after.
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.
Possible Complications
This condition is often fatal early in life.
When to Contact a Medical Professional
This condition is often diagnosed on the first examination of an infant.
