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]

ACMG classification

Our verdict: Benign. The variant received -15 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.76).
• BP6: Variant 10-98459649-T-C is Benign according to our data. Variant chr10-98459649-T-C is described in ClinVar as Benign. ClinVar VariationId is 738976.Status of the report is criteria_provided_single_submitter, 1 stars.
• BP7: Synonymous conserved (PhyloP=-0.497 with no splicing effect.
• BS1: Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.0000814 (119/1461852) while in subpopulation SAS AF = 0.000614 (53/86258). AF 95% confidence interval is 0.000482. There are 2 homozygotes in GnomAdExome4. There are 77 alleles in the male GnomAdExome4 subpopulation. Median coverage is 38. This position passed quality control check.
• BS2: High Homozygotes in GnomAdExome4 at 2 AR gene
