Genes affected

CD226 (HGNC:16961): (CD226 molecule) This gene encodes a glycoprotein expressed on the surface of NK cells, platelets, monocytes and a subset of T cells. It is a member of the Ig-superfamily containing 2 Ig-like domains of the V-set. The protein mediates cellular adhesion of platelets and megakaryocytic cells to vascular endothelial cells. The protein also plays a role in megakaryocytic cell maturation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2015]

The c.343C>A (p.Q115K) alteration is located in exon 3 (coding exon 2) of the CD226 gene. This alteration results from a C to A substitution at nucleotide position 343, causing the glutamine (Q) at amino acid position 115 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
