Genes affected

HS3ST2 (HGNC:5195): (heparan sulfate-glucosamine 3-sulfotransferase 2) 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 is a type II integral membrane protein and possesses heparan sulfate glucosaminyl 3-O-sulfotransferase activity. This gene is expressed predominantly in brain and may play a role in the nervous system. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.700C>T (p.R234C) alteration is located in exon 2 (coding exon 2) of the HS3ST2 gene. This alteration results from a C to T substitution at nucleotide position 700, causing the arginine (R) at amino acid position 234 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
