A rare condition present at birth that affects how cartilage and joints form, and can involve the skin and learning.

Understanding Chondrodysplasia punctata

Chondrodysplasia punctata is a rare condition present at birth that affects how cartilage and joints develop.

GARD lists small calcium deposits in cartilage, stiff joints with limited movement (contractures), intellectual disability, and dry, scaly skin (ichthyosis) as symptoms.

Signs & symptoms

Symptoms vary from person to person. GARD's summary describes these features:

  • Small calcium deposits in cartilage
  • Stiff joints with limited movement (contractures)

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

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