Very few kids are excluded from all grade levels because of a medical or mental problem, even if they need to take significant time off from school. The only medical diseases that would do this are very severe diseases that would affect a child's ability to get around, such as polio and cerebral palsy, but these conditions would not prevent a child from participating in school. At least in the US, if these children are able to participate and benefit from being in school, they will go to school. The mental illnesses that would prevent children from going to school would mostly be severe depression and severe anxiety disorders, like agoraphobia, which is a severe anxiety such that when one goes outside the house, he has severe anxiety, thought processing disorders like schizophrenia and post traumatic stress disorder. However, any mental disorder that is severe enough to keep a child home from school for 12 years is going to be severe enough that the child would most likely have problems learning during those years, making college not an immediate option. In addition, if a child had severe enough mental illness to keep him home from school, but he still managed to get an excellent eduation from learning from tutors or parents, he would still face the same mental problems going to college. So if a child had a severe mental illness that was so severe that it kept him from going to school, it probably would cause him not to be able to go to college as well. However, I found one example of a medical illness that looks like mental illness is sometimes seizures. See This. This case, some youngsters had seizures that looked like agoraphobia. However, these types of cases are rare, and would only rarely prevent a child from going to school, especially with good diagnosis and care. There are cases where gifted children were not able to fully benefit from school. For example, both Thomas Edision, the inventor, and Albert Einstein had attention deficit hyperactivity disorder (ADHD). Edison was taken out of school and Einstein was told that he was not going amount to anything by his teacher (his teacher was quite mistaken). However, ADHD is better recognized and rarely keeps kids out of school. As far as finding documented cases, I could not find any. You could try to search the web for organizations that deal with diseases like autism, ADHD, seizures, panic disorder, post traumatic stress disorder, agoraphobia, and schizophrenia and ask those organizations. I am sorry I do not have a simpler or better answer, but unfortunately, these are rare cases. Good luck!
