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]

The c.1231G>A (p.G411S) alteration is located in exon 4 (coding exon 3) of the GAL3ST4 gene. This alteration results from a G to A substitution at nucleotide position 1231, causing the glycine (G) at amino acid position 411 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
