The TEMPI Syndrome
tempisyndrome.org
Telangiectasias
Elevated Erythropoietin & Erythrocytosis
Monoclonal gammopathy (MGUS)
Perinephric fluid
Intrapulmonary shunting
The TEMPI Syndrome is a very rare orphan disease. Affected individuals typically display the five hallmarks from which the acronym is derived: telangiectasias, elevated erythropoietin and erythrocytosis, monoclonal gammopathy, perinephric fluid collections and intrapulmonary shunting. All patients have high erythropoietin levels and an MGUS (also called a Monoclonal Gammopathy of Undetermined Significance), but not all patients have perinephric fluid or intrapulmonary shunting early in the course of the disease.
​
As of January 2025, we are aware of ~49 people with TEMPI syndrome in the world.

2018 International TEMPI Symposium
On November 30, 2018 the first TEMPI symposium was held as part of the American Society of Hematology annual convention in San Diego, California. We brought together an international group of physicians to discuss the pathophysiology of this unusual condition and to put together a plan for sample collection and research to help best define treatment options for our patients.
