Genes affected

HPSE (HGNC:5164): (heparanase) Heparan sulfate proteoglycans are major components of the basement membrane and extracellular matrix. The protein encoded by this gene is an enzyme that cleaves heparan sulfate proteoglycans to permit cell movement through remodeling of the extracellular matrix. In addition, this cleavage can release bioactive molecules from the extracellular matrix. Several transcript variants encoding different isoforms have been found for this gene.

The c.791A>G (p.Y264C) alteration is located in exon 6 (coding exon 5) of the HPSE gene. This alteration results from a A to G substitution at nucleotide position 791, causing the tyrosine (Y) at amino acid position 264 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
