GABRA2 and Andersen-Tawil syndrome: Further analysis of sub network modules was conducted using the MCODE plugin in Cytoscape software 3.9.1 to screen for key genes involved in the antiepileptic effects of ATS, including gamma aminobutyric acid type A receptor genes (GABRA1, GABRA2, GABRA3, and GABRA5), gamma aminobutyric acid type A receptor beta 3 subunit (GABRB3), gamma aminobutyric acid type A receptor gamma 2 subunit (GABRG2), and glycine receptor alpha 1 subunit (GLRA1) (Figure 1A).
