Genes affected

HS6ST2 (HGNC:19133): (heparan sulfate 6-O-sulfotransferase 2) Heparan sulfate proteoglycans are ubiquitous components of the cell surface, extracellular matrix, and basement membranes, and interact with various ligands to influence cell growth, differentiation, adhesion, and migration. This gene encodes a member of the heparan sulfate (HS) sulfotransferase gene family, which catalyze the transfer of sulfate to HS. Different family members and isoforms are thought to synthesize heparan sulfates with tissue-specific structures and functions. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Ambry Genetics

Aug 13, 2021

The c.1640A>C (p.H547P) alteration is located in exon 6 (coding exon 5) of the HS6ST2 gene. This alteration results from a A to C substitution at nucleotide position 1640, causing the histidine (H) at amino acid position 547 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
