Overview
TTP may be classified according to ADAMTS13 gene mutations and autoantibody against ADAMTS13 into two subtypes: herditary syndromes, aquired syndromes.
Classification
TTP may be classified into several subtypes based on ADAMTS13 gene mutations(herditary syndromes) and autoantibody against ADAMTS13(aquired syndromes):[1][2]
1.Hereditary:
- Congenital TTP
- Inherited TTP
- Familial TTP
- Upshaw-Schulman syndrome (USS) is an autosomal recessive disease of ADAMTS13 gene on chromosome 9q34 .
2.Acquired
- Existence of an inhibitory antibody against ADAMTS13 due to the variety of conditions.
