Genes affected

CHST14 (HGNC:24464): (carbohydrate sulfotransferase 14) This gene encodes a member of the HNK-1 family of sulfotransferases. The encoded protein transfers sulfate to the C-4 hydroxyl of N-acetylgalactosamine residues in dermatan sulfate. Mutations in this gene have been associated with adducted thumb-clubfoot syndrome.[provided by RefSeq, Mar 2010]

Collection Method:clinical testing

The c.48G>T (p.E16D) alteration is located in exon 1 (coding exon 1) of the CHST14 gene. This alteration results from a G to T substitution at nucleotide position 48, causing the glutamic acid (E) at amino acid position 16 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
