Genes affected

CD109 (HGNC:21685): (CD109 molecule) This gene encodes a glycosyl phosphatidylinositol (GPI)-linked glycoprotein that localizes to the surface of platelets, activated T-cells, and endothelial cells. The protein binds to and negatively regulates signalling by transforming growth factor beta (TGF-beta). Multiple transcript variants encoding different isoforms have been found for this gene.

The c.79C>T (p.R27W) alteration is located in exon 2 (coding exon 2) of the CD109 gene. This alteration results from a C to T substitution at nucleotide position 79, causing the arginine (R) at amino acid position 27 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
