What is (are) Chondrocalcinosis 2 ?
Chondrocalcinosis 2 is a rare condition characterized by the accumulation of calcium pyrophosphate dihydrate crystals in and around the joints. A buildup of these crystals can lead to progressive (worsening over time) joint damage. Some affected people may not have any signs or symptoms of the condition. Others experience chronic joint pain or sudden, recurrent episodes of pain, stiffness and/or swelling of the joints. Although chondrocalcinosis 2 can affect people of all ages, it is most commonly diagnosed in early adulthood (age 20-40 years). It is caused by changes (mutations) in the ANKH gene and is inherited in an autosomal dominant manner. There is no cure for the condition and treatment is symptomatic.
