Genes affected

ANGPTL2 (HGNC:490): (angiopoietin like 2) Angiopoietins are members of the vascular endothelial growth factor family and the only known growth factors largely specific for vascular endothelium. Angiopoietin-1, angiopoietin-2, and angiopoietin-4 participate in the formation of blood vessels. ANGPTL2 protein is a secreted glycoprotein with homology to the angiopoietins and may exert a function on endothelial cells through autocrine or paracrine action. [provided by RefSeq, Jul 2008]

The c.343G>A (p.G115S) alteration is located in exon 2 (coding exon 1) of the ANGPTL2 gene. This alteration results from a G to A substitution at nucleotide position 343, causing the glycine (G) at amino acid position 115 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
