Genes affected

ADAMTS13 (HGNC:1366): (ADAM metallopeptidase with thrombospondin type 1 motif 13) This gene encodes a member of a family of proteins containing several distinct regions, including a metalloproteinase domain, a disintegrin-like domain, and a thrombospondin type 1 (TS) motif. The enzyme encoded by this gene specifically cleaves von Willebrand Factor (vWF). Defects in this gene are associated with thrombotic thrombocytopenic purpura. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]

ADAMTS13 (HGNC:):

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PM1: In a domain Disintegrin (size 96) in uniprot entity ATS13_HUMAN there are 5 pathogenic changes around while only 1 benign (83%) in NM_139027.6
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.992
