TEMPI syndrome



Other Names:
Telangiectasia - Erythrocytosis - Monoclonal gammopathy - Perinephric-fluid collections - Intrapulmonary shunting

TEMPI syndrome is a newly discovered, multisystem condition named for 5 characteristics that affected individuals have: Telangiectasias, Erythrocytosis with elevated erythropoietin level, Monoclonal gammopathy, Perinephric-fluid collections (fluid around the kidney), and Intrapulmonary shunting (when a region of the lungs is supplied with blood but with little or no ventilation).[1] Signs and symptoms of TEMPI syndrome have appeared in mid-adulthood in all known affected individuals. The telangiectasias develop mostly on the face, trunk and arms. The intrapulmonary shunt causes hypoxia (not enough oxygen supply), which slowly progresses until the person needs continuous supplemental oxygen to support their breathing. Blood clots and bleeding in the brain have also been reported in some affected individuals. The cause of TEMPI syndrome is currently unknown. Treatment has reportedly been completely or partially successful with the medication bortezomib.[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.
