"Luke is a patient currently receiving treatment at the Royal Liverpool Children's Trust for a very rare and complex illness.
"Doctors and nurses at the trust have explained to his parents the extremely poor outlook for Luke."
She added: "Rare cases such as this present a real ethical dilemma.
"Where there is a significant difference of opinion between paediatric medical specialists and parents, it may be necessary to put all the facts before a court for proper and impartial consideration. This is a difficult time for Luke's family and the doctors and nurses who are treating him.
"The trust is actively supporting the parents and will be reviewing the position carefully over the next 48 hours."
