Genes affected

HPSE2 (HGNC:18374): (heparanase 2 (inactive)) This gene encodes a heparanase enzyme. The encoded protein is a endoglycosidase that degrades heparin sulfate proteoglycans located on the extracellular matrix and cell surface. This protein may be involved in biological processes involving remodeling of the extracellular matrix including angiogenesis and tumor progression. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]

Ambry Genetics

Oct 03, 2022

The c.1707G>C (p.L569F) alteration is located in exon 12 (coding exon 12) of the HPSE2 gene. This alteration results from a G to C substitution at nucleotide position 1707, causing the leucine (L) at amino acid position 569 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
