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]

Ambry Genetics

Apr 13, 2022

The c.803C>T (p.T268I) alteration is located in exon 2 (coding exon 1) of the ANGPTL2 gene. This alteration results from a C to T substitution at nucleotide position 803, causing the threonine (T) at amino acid position 268 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
