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]

Variant summary: ADAMTS13 c.3070T>G (p.Cys1024Gly) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 3.2e-05 in 250648 control chromosomes. c.3070T>G has been reported in the literature in multiple homozygous individuals affected with Thrombotic Thrombocytopenic Purpura (Levy_2001, Del Orbe Barreto_2016, Beltrami-Moreira_2022). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 35022991, 27427187, 11586351). ClinVar contains an entry for this variant (Variation ID: 5803). Based on the evidence outlined above, the variant was classified as pathogenic. -

This sequence change replaces cysteine, which is neutral and slightly polar, with glycine, which is neutral and non-polar, at codon 1024 of the ADAMTS13 protein (p.Cys1024Gly). This variant is present in population databases (rs121908472, gnomAD 0.05%). This missense change has been observed in individuals with clinical features of thrombotic thrombocytopenic purpura (PMID: 11586351, 27427187, 30312976, 35022991; Invitae). ClinVar contains an entry for this variant (Variation ID: 5803). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. This variant disrupts the p.Cys1024 amino acid residue in ADAMTS13. Other variant(s) that disrupt this residue have been observed in individuals with ADAMTS13-related conditions (PMID: 21781265), which suggests that this may be a clinically significant amino acid residue. For these reasons, this variant has been classified as Pathogenic. -
