IP is inherited as an X linked dominant trait and is mostly inherited from the mother. While a few women may present with the condition as clinical cases, in others it may run in the germline as mosaicism and may not present clinically; though it can be passed on the child. The seizures described could be linked to the IP or could occur due to other reasons such as low blood sugar, electrolyte abnormalities etc. and it would be too premature to comment if this would be an early neurological sign. I would suggest discussing the situation and the expected prognosis in detail with a geneticist.
Hope the information is helpful.
