Genes affected

EGFL7 (HGNC:20594): (EGF like domain multiple 7) This gene encodes a secreted endothelial cell protein that contains two epidermal growth factor-like domains. The encoded protein may play a role in regulating vasculogenesis. This protein may be involved in the growth and proliferation of tumor cells. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Feb 2012]

Collection Method: clinical testing

The c.517G>A (p.G173S) alteration is located in exon 8 (coding exon 5) of the EGFL7 gene. This alteration results from a G to A substitution at nucleotide position 517, causing the glycine (G) at amino acid position 173 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
