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]

Computational evidence support a benign effect (BayesDel_noAF=-0.74).

BP6

Variant 9-133456673-G-A is Benign according to our data. Variant chr9-133456673-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 262448.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=-0.144 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00771 (1174/152308) while in subpopulation AFR AF = 0.0265 (1103/41554). AF 95% confidence interval is 0.0252. There are 11 homozygotes in GnomAd4. There are 559 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 11 AR gene
