CLCN2-Gen
Das CLCN2-Gen kodiert ein transmembranöses Protein, einen voltage-gated Chlorid-Kanal. Dieser ist für intrazelluläre Chlorid-Homöostase verantwortlich. Mutationen verursachen autosomal dominanten Hyperaldosteronismus, rezessive Leukenzephalopythie. Weitere genetische Varianten sind mit einer Anfälligkeit für Epilepsie in Zusammenhang gebracht.
