Preferred Label : Thrombotic thrombocytopenic purpura, hereditary;
Symbol : TTP;
CISMeF acronym : TTP;
Type : Phenotype, molecular basis known;
Alternative titles and symbols : Thrombotic microangiopathy, familial; Schulman-upshaw syndrome; USS; Microangiopathic hemolytic anemia, congenital; Thrombotic thrombocytopenic purpura, familial; Upshaw factor, deficiency of; Upshaw-schulman syndrome; Microangiopathic hemolytic anemia; Thrombotic thrombocytopenic purpura, hereditary, infantile- or adult-onset; Thrombotic thrombocytopenic purpura, congenital;
Description : The classic pentad of TTP includes hemolytic anemia with fragmentation of erythrocytes,
thrombocytopenia, diffuse and nonfocal neurologic findings, decreased renal function,
and fever. Congenital TTP, also known as Schulman-Upshaw syndrome, is characterized
by neonatal onset, response to fresh plasma infusion, and frequent relapses (Savasan
et al., 2003; Kokame et al., 2002). Acquired TTP, which is usually sporadic, usually
occurs in adults and is caused by an IgG inhibitor against the von Willebrand factor-cleaving
protease.;
Inheritance : Autosomal recessive;
Molecular basis : Caused by mutation in the von Willebrand-cleaving protease gene (ADAMTS13, 604134.0001);
Laboratory abnormalities : Decreased hemoglobin; Increased serum lactate dehydrogenase (LDH); Decreased serum haptoglobin; Proteinuria; Microscopic hematuria; Increased blood urea nitrogen (BUN); Increased creatinine; Ultra large von Willebrand factor (UL-vWF) in plasma;
