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]

Variant summary: NDST1 c.1831G>A (p.Gly611Ser) results in a non-conservative amino acid change located in the Sulfotransferase domain (IPR000863) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 8e-06 in 250738 control chromosomes (gnomAD). c.1831G>A has been reported in the literature as a homozygous mutation in multiple individuals affected with intellectual disability (e.g. Reuter_2014, Martinez_2017). These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. One ClinVar submitter (evaluation after 2014) cites the variant as likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. -

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 611 of the NDST1 protein (p.Gly611Ser). This variant is present in population databases (rs606231459, gnomAD 0.002%). This missense change has been observed in individuals with clinical features of intellectual disability (PMID: 25125150, 27620904; internal data). ClinVar contains an entry for this variant (Variation ID: 161412). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt NDST1 protein function with a positive predictive value of 80%. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -
