NDST3 and Behcet disease: The rs11098403 SNP is located within an intergenic region in the vicinity of the gene encoding N-deacetylase/N-sulfotransferase (heparan glucosaminyl) 3, (NDST3); the 5′ end of this gene is ~308 kb from this locus.7NDST3 is expressed abundantly in the hippocampus and cerebellum,8 in which structural and functional abnormalities are consistently observed in patients with schizophrenia9, 10 and BD.11 Therefore, this GWAS provided suggestive evidence that the NDST3 variation predisposed patients to schizophrenia and BD.
