Genes affected

NDST1 (HGNC:7680): (N-deacetylase and N-sulfotransferase 1) This gene encodes a member of the heparan sulfate/heparin GlcNAc N-deacetylase/ N-sulfotransferase family. The encoded enzyme is a type II transmembrane protein that resides in the Golgi apparatus. The encoded protein catalyzes the transfer of sulfate from 3'-phosphoadenosine 5'-phosphosulfate to nitrogen of glucosamine in heparan sulfate. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2014]

The c.1360C>T (p.R454C) alteration is located in exon 6 (coding exon 5) of the NDST1 gene. This alteration results from a C to T substitution at nucleotide position 1360, causing the arginine (R) at amino acid position 454 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
