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]

This 5-year old male with a history of global developmental delay, hyperkinesis, and mixed receptive-expressive language disorder was found to be compound heterozygous for two variants in the NDST1 gene. This variant is present in population databases at a frequency of 0.09% overall in ExAC and 0.11% in gnomAD. One homozygous individual was reported in gnomAD in an individual of non-Finnish European descent. Computational models predict this variant to be probably damaging to protein structure and/or function. This variant is located in the heparan sulfate N-deacetylase 1 domain of the protein. -
