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-related disorder Pathogenic:1
Likely pathogenic, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesJan 31, 2024The ADAMTS13 c.577C>T variant is predicted to result in the amino acid substitution p.Arg193Trp. This variant has been reported in the compound heterozygous and homozygous state in multiple individuals with thrombotic thrombocytopenic purpura (Matsumoto et al. 2004. PubMed ID: 14563640; Supplemental Table S1, van Dorland et al. 2019. PubMed ID: 30792199; Dai et al. 2020. PubMed ID: 33014938). In addition, the p.Arg193Trp change has been demonstrated to abolish ADAMTS13 enzymatic activity (Matsumoto et al. 2004. PubMed ID: 14563640; Pozzi et al. 2011. PubMed ID: 21937160). This variant is reported in 0.0029% of alleles in individuals of Latino descent in gnomAD . This variant is interpreted as likely pathogenic. -
