B3GALNT1 (Beta-1,3-N-Acetylgalactosaminyltransferase 1): B3GALNT1 is involved in glycosylation, a process essential for the proper function of many proteins. It synthesizes a type of glycan structure important for cell-cell adhesion and signaling. Mutations in B3GALNT1 can lead to muscular dystrophy-dystroglycanopathy, a group of disorders affecting muscle function....
