Although antibody targets characteristic of MG reportedly include muscle-specific kinase (MuSK) and lipoprotein-related protein 4 (LRP4) (3), antibodies to nicotinic acetylcholine receptor (nAChR) are the most common; they are detected in 85–90% of patients with generalized MG and in 50% of those with ocular MG (4). This evidence concerns the gene LRP4 and myasthenia gravis.
