Vitamin B6 allowed patients with ALDH7A1 and PNPO mutations to achieve seizure-free status, oxcarbazepine was effective for patients with SCN2A, ATP7A, WWOX, and PRRT2 mutations, and ACTH was partly effective for DOCK6 mutation patients with spasms and hypsarrhythmia. Here, ATP7A is linked to Hypsarrhythmia.
