Chondrocalcinoisis 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). 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. Chondrocalcinosis 2 is actually a familial form of chondrocalcinosis (also known as calcium pyrophosphate deposition disease or CPPD), which is caused by a similar buildup of CPP crystals but is associated with the aging process. The age-related chondrocalcinosis is quite common, whereas chondrocalcinosis 2 is not. In addition, people with chondrocalcinosis 2 are more likely to have symptoms that develop earlier in adulthood than the age-related form..
Chondrocalcinosis 2 is caused by changes in the ANKH gene. The disease is inherited in an autosomal dominant manner. Chondrocalcinosis 2 is diagnosed based on imaging such as X-rays. The diagnosis can be confirmed with genetic testing of the ANKH gene. Treatment may include the use of corticosteroids, pain relievers, and physical therapy.

:
Chondrocalcinosis 2, also known as
calcium pyrophosphate arthropathy, is related to
chondrocalcinosis and
familial calcium pyrophosphate deposition. An important gene associated with Chondrocalcinosis 2 is
ANKH (ANKH Inorganic Pyrophosphate Transport Regulator). The drugs
Bone Density Conservation Agents and
Calcium, Dietary have been mentioned in the context of this disorder. Affiliated tissues include
testes and
bone, and related phenotypes are
osteoarthritis and
arthropathy

Chondrocalcinosis, or cartilage calcification, is a common condition that usually results from deposition of crystals of calcium pyrophosphate dihydrate (CPPD) in articular hyaline and fibro-cartilage. CPPD crystal deposition may be asymptomatic or associated with characteristic acute attacks ('pseudogout') or chronic arthritis. It can be detected radiographically. Chondrocalcinosis occurs in 3 forms: a primary hereditary form (e.g., CCAL2); a form associated with metabolic disorders (e.g., hyperparathyroidism, hemochromatosis, and hypomagnesemia), and a sporadic form, which may in some cases represent the hereditary form (summary by Hughes et al., 1995 and Richette et al., 2009).

Chondrocalcinosis 2: Chondrocalcinosis is a common cause of joint pain and arthritis caused by calcium deposition in articular cartilage and the presence of calcium hypophosphate crystals in synovial fluid, cartilage and periarticular soft tissue. CCAL2 inheritance is autosomal dominant.
