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]

RALGPS1 (HGNC:16851): (Ral GEF with PH domain and SH3 binding motif 1) Enables guanyl-nucleotide exchange factor activity. Involved in regulation of Ral protein signal transduction. Predicted to be located in cytoplasm and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.1378A>G (p.S460G) alteration is located in exon 5 (coding exon 4) of the ANGPTL2 gene. This alteration results from a A to G substitution at nucleotide position 1378, causing the serine (S) at amino acid position 460 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
