Therefore, this variant has been classified as Likely Pathogenic. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt NDST1 protein function. ClinVar contains an entry for this variant (Variation ID: 161412). This missense change has been observed in individuals with clinical features of intellectual disability (PMID: 25125150, 27620904; Invitae). This variant is present in population databases (rs606231459, gnomAD 0.002%).

(2014) identified a homozygous c.1831G-A transition in the NDST1 gene, resulting in a gly611-to-ser (G611S) substitution at a highly conserved residue near the 3-prime-phosphoadenosine 5-prime-phosphate (PAP)-binding site in the sulfotransferase domain. The mutation, which was confirmed by Sanger sequencing, segregated with the disorder in the family and was not present in the dbSNP (build 137), 1000 Genomes Project, or Exome Variant Server databases, or in ethnically matched controls.

Comment:

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).

Comment:

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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt NDST1 protein function. ClinVar contains an entry for this variant (Variation ID: 161412). This missense change has been observed in individuals with clinical features of intellectual disability (PMID: 25125150, 27620904; Invitae). This variant is present in population databases (rs606231459, gnomAD 0.002%). 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).
