The youngster has spent most of his life in hospital battling Pompe disease, a rare and debilitating condition which affects the muscles and the heart.
But he could soon have his own custom-made bedroom, fitted with all the medical equipment he needs to survive, thanks to the donation by Mr Trump.
Sean's muscles are weak and floppy and he needs a ventilator to breathe properly. After being critically ill in hospital, he is now back at home living with his mother and father, but he requires round-the-clock care, and the size of his current bedroom has made caring for Sean extremely difficult.
The Tye family, have been given permission to convert a double garage into a new bedroom for Sean but the family needs £43,000 to complete the job.
Aberdeenshire Council is already providing £15,000 of funding and Mr Trump has added another £10,000 to the fund. His contribution went to Aberdeenshire Care and Repair, who are co-ordinating the work on behalf of the family.
When Sean was just two, he spent four-and-a-half months in Glasgow's Yorkhill children's hospital fighting for his life. His parents were told that he wouldn't reach his first birthday, but Sean has constantly defied medical odds, despite being born with a condition that only affects 1 in 40,000 people.
Mr Tye said: "He has been on a significant journey and has proved everybody wrong. Doctors said his heart is now improving."
