Genes affected

ANGPTL1 (HGNC:489): (angiopoietin like 1) 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. The protein encoded by this gene is another member of the angiopoietin family that is widely expressed in adult tissues with mRNA levels highest in highly vascularized tissues. This protein was found to be a secretory protein that does not act as an endothelial cell mitogen in vitro. [provided by RefSeq, Jul 2008]

RALGPS2 (HGNC:30279): (Ral GEF with PH domain and SH3 binding motif 2) Predicted to enable guanyl-nucleotide exchange factor activity. Predicted to be involved in regulation of Ral protein signal transduction; regulation of catalytic activity; and small GTPase mediated signal transduction. Predicted to be located in cytoplasm and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

The c.1261C>G (p.L421V) alteration is located in exon 5 (coding exon 3) of the ANGPTL1 gene. This alteration results from a C to G substitution at nucleotide position 1261, causing the leucine (L) at amino acid position 421 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
