Genes affected

HS3ST1 (HGNC:5194): (heparan sulfate-glucosamine 3-sulfotransferase 1) Heparan sulfate biosynthetic enzymes are key components in generating a myriad of distinct heparan sulfate fine structures that carry out multiple biologic activities. The enzyme encoded by this gene is a member of the heparan sulfate biosynthetic enzyme family. It possesses both heparan sulfate glucosaminyl 3-O-sulfotransferase activity, anticoagulant heparan sulfate conversion activity, and is a rate limiting enzyme for synthesis of anticoagulant heparan. This enzyme is an intraluminal Golgi resident protein. [provided by RefSeq, Jul 2008]

The c.772C>T (p.R258W) alteration is located in exon 2 (coding exon 1) of the HS3ST1 gene. This alteration results from a C to T substitution at nucleotide position 772, causing the arginine (R) at amino acid position 258 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
