Living with Camptomelic dysplasia

A condition that mainly affects how the bones, reproductive system, and other body parts form before birth.

Understanding Camptomelic dysplasia

Campomelic dysplasia is a disorder that affects development of the skeleton, the reproductive system, and other parts of the body.

The name comes from Greek words for "bent limb." Babies are typically born with bowed leg bones, and sometimes bowed arm bones. Many also have short legs, dislocated hips, a small chin, a flat face, and a large head for their body size. Bone changes begin before birth and can often be seen on ultrasound.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Bowed leg bones, sometimes with skin dimples
  • Dislocated hips
  • Clubfeet (feet turned inward and upward)
  • 11 pairs of ribs instead of 12
  • Cleft palate and a small lower jaw
  • External genitalia that may not look clearly male or female

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include bone and joint specialists, brain and nervous system specialists, genetic specialists and hormone specialists.

  3. Consider genetic testing

    Changes in SOX9 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Little People of America may keep lists of experts for this condition.

Quick facts

GenesSOX9

Campomelic dysplasia is linked to changes in the SOX9 gene. It is inherited in an autosomal dominant way, which means one changed copy of the gene can cause the condition.
