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.1049C>T (p.T350M) alteration is located in exon 10 (coding exon 10) of the GALNT14 gene. This alteration results from a C to T substitution at nucleotide position 1049, causing the threonine (T) at amino acid position 350 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
