What are the symptoms of Antisynthetase syndrome ?
What are the signs and symptoms of Antisynthetase syndrome? The signs and symptoms of antisynthetase syndrome vary but may include: Fever Loss of appetite Weight loss Muscle inflammation (myositis) Inflammation of multiple joints (polyarthritis) Interstitial lung disease (causing shortness of breath, coughing, and/or dysphagia) Mechanic's hands (thickened skin of tips and margins of the fingers) Raynaud phenomenon Some studies suggest that affected people may be at an increased risk for various types of cancer, as well. The Human Phenotype Ontology provides the following list of signs and symptoms for Antisynthetase syndrome. 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.

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.
