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]

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 89). This premature translational stop signal has been observed in individual(s) with clinical features of urofacial syndrome (PMID: 20560210, 27151922). This variant is present in population databases (rs267606865, gnomAD 0.005%). This sequence change creates a premature translational stop signal (p.Arg153*) in the HPSE2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in HPSE2 are known to be pathogenic (PMID: 20560210, 25510506).
