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

Sep 04, 2024

The c.1808A>G (p.N603S) alteration is located in exon 12 (coding exon 11) of the THBS1 gene. This alteration results from a A to G substitution at nucleotide position 1808, causing the asparagine (N) at amino acid position 603 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
