What are the symptoms of Chondrocalcinosis 2 ?
What are the signs and symptoms of Chondrocalcinosis 2? The signs and symptoms of chondrocalcinosis 2 vary from person to person. Some affected people may not have any symptoms of the condition aside from the appearance of calcium deposits on joint x-rays. Others experience chronic pain in affected joints and/or the back if calcium deposits develop around the bones of the spine. Chondrocalcinosis 2 can also be associated with sudden, recurrent episodes of joint pain, stiffness and/or swelling that can last anywhere from several hours to several weeks. These episodes can lead to limited range of motion in the affected joint or even ankylosis (fixation of joint in place). Although almost any joint in the body can be affected, symptoms are often confined to a single knee, wrist, hip or shoulder. The Human Phenotype Ontology provides the following list of signs and symptoms for Chondrocalcinosis 2. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Abnormality of the intervertebral disk 90% Arthralgia 90% Calcification of cartilage 90% Joint swelling 90% Osteoarthritis 50% Abnormal tendon morphology 7.5% Chondrocalcinosis 7.5% Joint dislocation 7.5% Limitation of joint mobility 7.5% Seizures 7.5% Adult onset - Arthropathy - Autosomal dominant inheritance - Polyarticular chondrocalcinosis - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
