Living with Vitamin D-dependent rickets
A group of inherited conditions that make bones soft and weak, beginning within months after birth.
Understanding Vitamin D-dependent rickets
There are several types, based on genetic cause: 1A, 1B, 2A, and a very rare 2B. Signs begin within months after birth. Weak bones can cause bone pain, slow growth, and fractures. Children may develop bowed legs once they walk. Some have tooth problems, low muscle tone, or seizures.
Signs & symptoms
GARD doesn't list a common-symptom list, but its summary describes these:
- Soft, weak bones (rickets)
- Bone pain
- Slow growth
- Bowed legs
- Easily broken bones
- Thin tooth enamel and cavities
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
