The addition of N-acetylglucosamine (GlcNAc) O-linked to serine and threonine residues of proteins is known as O-GlcNAc. This post-translational modification is found within multicellular eukaryotes on hundreds of nuclear and cytoplasmic proteins. O-GlcNAc transferase (OGT) installs O-GlcNAc onto target proteins

A 12 year-old female presented with a seven-year history of progressive muscle weakness, atrophy, tremor and fasciculations. Cognition was normal. Rectal biopsy revealed intracellular storage material and biochemical testing indicated low hexosaminidase activity consistent with juvenile-onset G(M2)-gangliosidosis. Genetic evaluation revealed
