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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 08, 2023The c.1544G>A (p.R515H) alteration is located in exon 10 (coding exon 9) of the THBS1 gene. This alteration results from a G to A substitution at nucleotide position 1544, causing the arginine (R) at amino acid position 515 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
