Genes affected
HS6ST3 (HGNC:19134): (heparan sulfate 6-O-sulfotransferase 3) Heparan sulfate (HS) sulfotransferases, such as HS6ST3, modify HS to generate structures required for interactions between HS and a variety of proteins. These interactions are implicated in proliferation and differentiation, adhesion, migration, inflammation, blood coagulation, and other diverse processes (Habuchi et al., 2000 [PubMed 10644753]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 16, 2024The c.359T>C (p.L120P) alteration is located in exon 1 (coding exon 1) of the HS6ST3 gene. This alteration results from a T to C substitution at nucleotide position 359, causing the leucine (L) at amino acid position 120 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
