Disease Profile
Chondrocalcinosis 2
Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.

Inheritance
Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease.
Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype.
X-linked
dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.

X-linked
recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.
recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.
Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.
Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Summary
Chondrocalcinosis 2 is a rare disease characterized by the accumulation of calcium pyrophosphate dihydrate (CPP) crystals in and around the joints. A buildup of these crystals can lead to joint pain and damage that is progressive (worsens over time).[1][2] Signs and symptoms of the disease include chronic joint pain or sudden, recurrent episodes of pain, as well as stiffness or swelling of the joints.[1][2][3] Chondrocalcinosis 2 is actually a

Symptoms
The symptoms can be chronic (occurring all the time) or may occur in sudden episodes. If the pain occurs in episodes, it can last anywhere from several hours to several weeks.[2][3] In some cases, episodes of pain may cause fevers.[5] The attack may affect only one joint or multiple joints. Joints that are most commonly affected include the knees, wrists, hips, or shoulders.[1][2] Some people with chondrocalcinosis 2 may experience pain in the back if calcium deposits develop around the bones of the spine.[2][3]
This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Diagnosis
If a doctor suspects that a person has chondrocalcinosis caused by a change (pathogenic variation) in the ANKH
Testing Resources
- The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.
Treatment
- Joint aspiration (draining of fluid from the affected joint)
Corticosteroid injections- Non-steroidal anti-inflammatory drugs (NSAIDs), including aspirin or ibuprofen
For people who have frequent episodes of pain or for whom other medications are not effective, small doses of a medication called colchicine may be recommended. However, this medication has side effects and may not help everyone with chondrocalcinosis 2.[1]
In some cases, people with chondrocalcinosis 2 may be required to wear a splint or brace to prevent too much movement. In other cases,

Differential diagnosis includes other genetic conditions causing secondary CC such as chronic hypomagnesaemia, Gitelman syndrome, rare hereditary hemochromatosis and hypophosphatasia (see these terms). CPPD can also occur sporadically but it is a separate, much more common entity, with aging being the most important risk factor.
