Genes affected

GCNT4 (HGNC:17973): (glucosaminyl (N-acetyl) transferase 4) Predicted to enable acetylglucosaminyltransferase activity. Predicted to be involved in O-glycan processing and carbohydrate metabolic process. Predicted to act upstream of or within several processes, including inter-male aggressive behavior; kidney morphogenesis; and thyroid hormone metabolic process. Predicted to be located in Golgi membrane. [provided by Alliance of Genome Resources, Apr 2022]
