Genes affected
GALNT14 (HGNC:22946): (polypeptide N-acetylgalactosaminyltransferase 14) This gene encodes a Golgi protein which is a member of the polypeptide N-acetylgalactosaminyltransferase (ppGalNAc-Ts) protein family. These enzymes catalyze the transfer of N-acetyl-D-galactosamine (GalNAc) to the hydroxyl groups on serines and threonines in target peptides. The encoded protein has been shown to transfer GalNAc to large proteins like mucins. Alterations in this gene may play a role in cancer progression and response to chemotherapy.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2024The c.1202A>C (p.K401T) alteration is located in exon 12 (coding exon 12) of the GALNT14 gene. This alteration results from a A to C substitution at nucleotide position 1202, causing the lysine (K) at amino acid position 401 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
