N-Acetylgalactosaminyltransferase 12 (GALNT12) is part of the UDP-N-acetylgalactosamine gene family and plays a role in the biological processes of various diseases, including tumor progression. It is a potential biomarker for fibrosarcoma, and its high expression levels are closely associated with the yes1 associated transcriptional regulator (YAP1) signaling pathway.
