Genes affected
GAL3ST4 (HGNC:24145): (galactose-3-O-sulfotransferase 4) This gene encodes a member of the galactose-3-O-sulfotransferase protein family. The product of this gene catalyzes sulfonation by transferring a sulfate to the C-3' position of galactose residues in O-linked glycoproteins. This enzyme is highly specific for core 1 structures, with asialofetuin, Gal-beta-1,3-GalNAc and Gal-beta-1,3 (GlcNAc-beta-1,6)GalNAc being good substrates. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 20, 2021The c.1132T>C (p.W378R) alteration is located in exon 4 (coding exon 3) of the GAL3ST4 gene. This alteration results from a T to C substitution at nucleotide position 1132, causing the tryptophan (W) at amino acid position 378 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
