Genes affected
HS6ST1 (HGNC:5201): (heparan sulfate 6-O-sulfotransferase 1) The protein encoded by this gene is a member of the heparan sulfate biosynthetic enzyme family. Heparan sulfate biosynthetic enzymes are key components in generating a myriad of distinct heparan sulfate fine structures that carry out multiple biological activities. This enzyme is a type II integral membrane protein and is responsible for 6-O-sulfation of heparan sulfate. This enzyme does not share significant sequence similarity with other known sulfotransferases. A pseudogene located on chromosome 1 has been found for this gene. [provided by RefSeq, Jul 2008]

The c.1133G>A (p.R378H) alteration is located in exon 2 (coding exon 2) of the HS6ST1 gene. This alteration results from a G to A substitution at nucleotide position 1133, causing the arginine (R) at amino acid position 378 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
