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]

The c.1226A>G (p.D409G) alteration is located in exon 6 (coding exon 5) of the HS6ST2 gene. This alteration results from a A to G substitution at nucleotide position 1226, causing the aspartic acid (D) at amino acid position 409 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
