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]

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 25, 2021For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects ADAMTS13 function (PMID: 22783805). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 5801). This missense change has been observed in individual(s) with thrombotic thrombocytopenic purpura (PMID: 11586351, 14512317, 22783805, 29554699). In at least one individual the data is consistent with the variant being in trans (on the opposite chromosome) from a pathogenic variant. This variant is present in population databases (rs121908470, gnomAD 0.004%). This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 196 of the ADAMTS13 protein (p.Thr196Ile). -
