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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 25, 2023The c.1121A>C (p.H374P) alteration is located in exon 2 (coding exon 1) of the CHST2 gene. This alteration results from a A to C substitution at nucleotide position 1121, causing the histidine (H) at amino acid position 374 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
