Genes affected

NDST2 (HGNC:7681): (N-deacetylase and N-sulfotransferase 2) This gene encodes a member of the N-deacetylase/N-sulfotransferase subfamily of the sulfotransferase 1 proteins. The encoded enzyme has dual functions in processing glucosamine and heparin polymers, including N-deacetylation and N-sulfation. The encoded protein may be localized to the Golgi.

The c.2489G>A (p.R830Q) alteration is located in exon 14 (coding exon 12) of the NDST2 gene. This alteration results from a G to A substitution at nucleotide position 2489, causing the arginine (R) at amino acid position 830 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
