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.842C>T (p.T281I) alteration is located in exon 8 (coding exon 8) of the CD109 gene. This alteration results from a C to T substitution at nucleotide position 842, causing the threonine (T) at amino acid position 281 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
