Genes affected

THBS1 (HGNC:11785): (thrombospondin 1) The protein encoded by this gene is a subunit of a disulfide-linked homotrimeric protein. This protein is an adhesive glycoprotein that mediates cell-to-cell and cell-to-matrix interactions. This protein can bind to fibrinogen, fibronectin, laminin, type V collagen and integrins alpha-V/beta-1. This protein has been shown to play roles in platelet aggregation, angiogenesis, and tumorigenesis. [provided by RefSeq, Jul 2008]

Ambry Genetics

Oct 26, 2022

The c.2012A>G (p.D671G) alteration is located in exon 13 (coding exon 12) of the THBS1 gene. This alteration results from a A to G substitution at nucleotide position 2012, causing the aspartic acid (D) at amino acid position 671 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
