Living with Chondrocalcinosis 1

An inherited joint condition where calcium crystals build up in joint tissue and cause severe wear-and-tear arthritis.

Understanding Chondrocalcinosis 1

Chondrocalcinosis 1 (CCAL1) is an inherited rheumatologic (joint) disease where calcium-containing crystals build up in joint tissue.

It leads to severe degenerative osteoarthritis. GARD says it is linked to changes on chromosome 8q.

Signs & symptoms

GARD doesn't list specific symptoms for this condition, but the summary describes these features:

  • Calcium crystals in joint tissue
  • Severe wear-and-tear arthritis (osteoarthritis)

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

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

Everyday life

Living with a rare condition is easier with support.

  • Connect with rare disease patient organizations for support
  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
Bring these questions to your next doctor visit
Which joints are most affected, and what can protect them?
Is genetic testing available for our family?
Which specialists, such as rheumatologists, should be on my care team?

Quick facts

InheritanceAutosomal Dominant

GARD says changes on chromosome 8q cause this condition. It is autosomal dominant, so one changed copy of the gene can be enough.

Also known as: ccal1; chondrocalcinosis with early-onset osteoarthritis
