Genes affected

CHST10 (HGNC:19650): (carbohydrate sulfotransferase 10) This protein encoded by this gene transfers sulfate to the C-3 hydroxyl of terminal glucuronic acid of protein- and lipid-linked oligosaccharides. This protein was first identified as a sulfotransferase that acts on the human natural killer-1 (HNK-1) glycan; HNK-1 is a carbohydrate involved in neurodevelopment and synaptic plasticity.[provided by RefSeq, Feb 2011]

The c.733G>A (p.G245S) alteration is located in exon 7 (coding exon 5) of the CHST10 gene. This alteration results from a G to A substitution at nucleotide position 733, causing the glycine (G) at amino acid position 245 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
