Genes affected
HS3ST4 (HGNC:5200): (heparan sulfate-glucosamine 3-sulfotransferase 4) This gene encodes the enzyme heparan sulfate D-glucosaminyl 3-O-sulfotransferase 4. This enzyme generates 3-O-sulfated glucosaminyl residues in heparan sulfate. Cell surface heparan sulfate is used as a receptor by herpes simplex virus type 1 (HSV-1), and expression of this gene is thought to play a role in HSV-1 pathogenesis. [provided by RefSeq, Jul 2008]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 08, 2024The c.47C>T (p.P16L) alteration is located in exon 1 (coding exon 1) of the HS3ST4 gene. This alteration results from a C to T substitution at nucleotide position 47, causing the proline (P) at amino acid position 16 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
