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.

The c.1276C>G (p.Q426E) alteration is located in exon 13 (coding exon 13) of the GALNT14 gene. This alteration results from a C to G substitution at nucleotide position 1276, causing the glutamine (Q) at amino acid position 426 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
