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.179C>T (p.P60L) alteration is located in exon 2 (coding exon 1) of the NDST1 gene. This alteration results from a C to T substitution at nucleotide position 179, causing the proline (P) at amino acid position 60 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
