Hereditary thrombotic thrombocytopenic purpura, also called Upshaw‐Schulman syndrome (USS), is a rare disease caused by genetic mutations in the ADAMTS13 gene, which severely decrease the activity of ADAMTS13, a metalloprotease that cleaves von Willebrand factor multimers (VWF). Genotypically identical patients can show great phenotypic diversity.
