Hmmm. I am on a maintenance dose of Phenobarbitol for seizures. My aunt (on my mom's side) also has seizures, and my great aunt (mom's father's sister) has narcolepsi. My great-grandmother's family (mom's dad's mother) almost all were cross-eyed. (I've got a photo I can scan and post). My mom had facial hair, was overweight and had other conditions that could have been attributed to a weakened adrenal gland. Of course my great-grandmother's family were a very fun, intelligent and witty lot. They were notorious in the area for their sense of humor. One even served in the State House of Representatives. As for the Corpus Callosum. Men generally have a thicker separator between the hemispheres of the brain than women. The difference it creates is the ability of women to "intuitivelly" solve problems by using both halves of the brian in conjuction, and the ability of men to be able to compartmentalize their thoughts and focus better. There are only weaknesses when you don't take advantage of the strengths. It has been reported that most of the people who were considered geniuses through history also suffered from seizures. Your son's condition may be a strength rather than a burden. Once the seizure activity is controlled he might actually be able to use the added communication between the hemispheres to his advantage.
