Genetic Variant NM_021828.5:c.1682G>A (chr10-98459671-C-T) – ACMG Classification: Likely_benign (-1 pts)

Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP4

The NM_021828.5(HPSE2):c.1682G>A(p.Arg561His) variant causes a missense change. The variant allele was found at a frequency of 0.0000217 in 1,614,062 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R561S) has been classified as Uncertain significance.

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]
