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 21, 2021

The c.235G>A (p.V79M) alteration is located in exon 3 (coding exon 2) of the THBS1 gene. This alteration results from a G to A substitution at nucleotide position 235, causing the valine (V) at amino acid position 79 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
