My son has two cafe au lait spots and possible epilepsy (nocturnal seizures). doctor mentioned genetic disorder. is it possible?

Confusing question: Cafe au lait spots are often part of neurofibromatosis, a disorder that can arise as a new mutation in the genes or be passed from a parent. Kids with > 6 spots > 5mm in diameter or adolescents >15mm diameter may have the disorder, but the spots are randomly found on normal people.Discuss with your pediatrician.

Yes, it is possible: Whenever a child has more than one thing going on, or one thing (e.g. Seizures) and additional physical findings (e.g. Cafe au lait spots) the possibility of a genetic condition behind findings increases. Both seizures and cafe au lait spots separately are relatively common. Combination increases, but does not diagnose, a genetic cause. I would recommend formal evaluation by a clinical geneticist.
