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]

This variant is not present in population databases (gnomAD no frequency). This sequence change affects the initiator methionine of the CHST14 mRNA. The next in-frame methionine is located at codon 44. This variant has not been reported in the literature in individuals affected with CHST14-related conditions. ClinVar contains an entry for this variant (Variation ID: 2004232). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
