Genes affected

SULF2 (HGNC:20392): (sulfatase 2) Heparan sulfate proteoglycans (HSPGs) act as coreceptors for numerous heparin-binding growth factors and cytokines and are involved in cell signaling. Heparan sulfate 6-O-endosulfatases, such as SULF2, selectively remove 6-O-sulfate groups from heparan sulfate. This activity modulates the effects of heparan sulfate by altering binding sites for signaling molecules (Dai et al., 2005 [PubMed 16192265]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Mar 14, 2023

The c.1946G>A (p.R649Q) alteration is located in exon 14 (coding exon 13) of the SULF2 gene. This alteration results from a G to A substitution at nucleotide position 1946, causing the arginine (R) at amino acid position 649 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
