Hereditary Thrombotic Thrombocytopenic Purpura (hTTP) or Upshaw-Schulman Syndrome (USS) is an ultra-rare and complex blood coagulation disease

«The fact that the medical research of a son of the Mississippi Delta, born in Louise, MS in 1929, is being continued by a team of researchers all over the world, still excites me!»
Daughter of Dr. Jefferson D. Upshaw

The Hereditary TTP Registry participated in the first-in-human study evaluating a recombinant human ADAMTS13 as therapeutic option in the treatment of congenital TTP
