   * 40% of individuals with PNPO deficiency are responsive to pyridoxine (PN) and seizures. In a majority of these patients seizures will remit within 1 to 3 days, but it could take upto several days in some cases   * 40% of individuals with PNPO deficiency are responsive to pyridoxine (PN) and seizures.
