Re. the autism and transplant... it may not even come down to being their decision. Many centers will disqualify someone from eligibility for transplant if they have other co-existing conditions like this. As wrong as it sounds, there was a recent case where CHOP denied a young girl from being placed on the list for a kidney transplant because she had developmental disabilities in addition to her kidney disease. Due to the enormous PR backlash, they decided to allow a family member donate a kidney (which was what the family wanted in the first place!), but initially they were not going to even allow that.
