Arlo McArthur, three, was first diagnosed with Wiskott-Aldrich Syndrome when he was just ten weeks old. The only potential cure was through a stem cell transplant from an unrelated donor, which was unsuccessful. Now Arlo’s disease has returned, he needs a second transplant to survive. Arlo has three matches on the register already, but doctors say they are all too old and can’t take the risk again. The youngsters family, from Milngavie, are appealing for people to support blood cancer charity Anthony Nolan in raising urgent funds to add more donors to the stem cells register and give their little boy the best possible chance of survival.
