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]

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. This variant has not been reported in the literature in individuals affected with NDST1-related conditions. This variant is present in population databases (rs761957648, gnomAD 0.006%). This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 66 of the NDST1 protein (p.Arg66His). -
