SCN4A and neurodegenerative disease: In whole-exome sequencing of six AIP patients the researchers found several pathogenic gene variants associated with neurodegenerative diseases, including UNC13A, ALG8, FBXO38, AGRN, DOK7, and SCN4A. AGRN, DOK7, and SCN4A genes were associated with congenital myasthenic syndromes (CMS), the symptoms of which are significantly similar to the neurological features of AIP attacks.
