Genes affected

HS3ST3A1 (HGNC:5196): (heparan sulfate-glucosamine 3-sulfotransferase 3A1) 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. The sulfotransferase domain of this enzyme is highly similar to the same domain of heparan sulfate D-glucosaminyl 3-O-sulfotransferase 3B1, and these two enzymes sulfate an identical disaccharide. This gene is widely expressed, with the most abundant expression in liver and placenta. [provided by RefSeq, Dec 2014]

The c.1153G>C (p.E385Q) alteration is located in exon 2 (coding exon 2) of the HS3ST3A1 gene. This alteration results from a G to C substitution at nucleotide position 1153, causing the glutamic acid (E) at amino acid position 385 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
