Genes affected

ANGPT4 (HGNC:487): (angiopoietin 4) Angiopoietins are proteins with important roles in vascular development and angiogenesis. All angiopoietins bind with similar affinity to an endothelial cell-specific tyrosine-protein kinase receptor. The mechanism by which they contribute to angiogenesis is thought to involve regulation of endothelial cell interactions with supporting perivascular cells. The protein encoded by this gene functions as an agonist and is an angiopoietin. [provided by RefSeq, Jul 2008]

The c.626A>T (p.Q209L) alteration is located in exon 4 (coding exon 4) of the ANGPT4 gene. This alteration results from a A to T substitution at nucleotide position 626, causing the glutamine (Q) at amino acid position 209 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
