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.

Collection Method: clinical testing

The c.596C>T (p.P199L) alteration is located in exon 5 (coding exon 5) of the CD109 gene. This alteration results from a C to T substitution at nucleotide position 596, causing the proline (P) at amino acid position 199 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
