A TWAS study involving 1,873 MG patients utilized gene expression profiles from skeletal muscle, whole blood, and tibial nerve to identify expression quantitative trait loci (eQTLs) significantly associated with MG in the nicotinic cholinergic receptor α1 subunit (CHRNA1) and β1 subunit (CHRNB1) genes, respectively (14). This evidence concerns the gene CHRNA1 and myasthenia gravis.
