My understanding is that this was not medically possible?
"While the donation will pay for the procedure, the Knights still have to come up with travel expenses before they can go. Last time, the total cost was $7,300. After Trinity receives the second treatment, she will need a third $5,000 treatment, the Knights said, and then a $25,000 procedure which calls for actually putting the elastin gene in her. The elastin missing in Trinity is what causes Williams Syndrome."
