Structure of ADAMTS13 and mutations in congenital thrombotic thrombocytopenic purpura.
The ADAMTS13 gene (A) contains 29 exons in ∼ 37 kb on chromosome 9q34. Dashed lines show the relationship of exons to the ADAMTS13 protein (B). Structural domains include signal peptide (S), propeptide (P), metalloprotease, disintegrin domain (Dis), thrombospondin 1 repeats (numbered 1-8), cysteine-rich domain (Cys), spacer domain, and CUB domains. Mutations in patients with inherited TTP are shown (C).
