Genes affected

CHST2 (HGNC:1970): (carbohydrate sulfotransferase 2) This locus encodes a sulfotransferase protein. The encoded enzyme catalyzes the sulfation of a nonreducing N-acetylglucosamine residue, and may play a role in biosynthesis of 6-sulfosialyl Lewis X antigen. [provided by RefSeq, Aug 2011]

The c.400G>C (p.G134R) alteration is located in exon 2 (coding exon 1) of the CHST2 gene. This alteration results from a G to C substitution at nucleotide position 400, causing the glycine (G) at amino acid position 134 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
