ANDREW and Judy Kim are still searching the globe for a donor for their two-year-old son after he was diagnosed with a rare genetic condition.

The couple's son Alastair was diagnosed with chronic granulomatous disorder (CGD) in February last year.

Mr and Mrs Kim launched an appeal for help in September but the search is still on for a matching donor and their son still needs hospital treatment.

The life-threatening condition wipes out his immune system, meaning even the most minor infections leave him seriously ill.

A course of genetic therapy treatment to help him fight infections has been launched and Alastair has been treated at Oxford Children's Hospital and Great Ormond Street Hospital in London.

The only hope of a permanent cure lies in a bone marrow stem cell donor but it needs to be a 90 per cent genetic match and the family is calling for more East Asians to sign up as donors.

Mr Kim, 37, a medical research engineer, said: "It is not easy to find a match and we pray every day that it will work out.

"We have to make sure that Alastair does not get a cut because it could get infected and he does not have the ability to fight off bacteria.

"That could cascade down the line to something very dangerous for him.

"If we get ill then we have to stay away from him – he loves our dog Choco Pie but he is not allowed to stroke her.

"We are doing our best to stay positive and raise awareness about his condition."

Mr and Mrs Kim, who live near Longworth with their other son Micah, five, have already searched the international register of more than four million donors but without success.

They are both of Korean descent so a matching donor will most likely be of Korean, Japanese or Chinese heritage.

The number of East Asians on international donor registers is very limited – of the 617,000 registered donors in the UK just 0.5 per cent are east Asian.

The couple, who moved to Oxfordshire from Chicago nine years ago, are now appealing for people around the world, particularly East Asians, to order a free kit through a website they have set up, and take a two-minute home test to see if they could help.

Alastair has had numerous infections since he was born in September 2014.

He spent the first year-and-a-half of his life in and out of hospital but CGD is so rare, doctors never thought to test him for it but eventually a doctor at the John Radcliffe Hospital in Oxford decided to test Alastair for the condition.

The couple desperately want to find a matching donor, but also want to increase the number of East Asians on the donor register.

The couple have run several blood drives at Mrs Kim's office at Oxford University and at Harwell Oxford.

More than 90 people came forward and of those, five were able to donate blood that helped Alastair to fight infections.

Mr Kim added: "At a couple of blood drives we have found matches for other people and hopefully one day a match will found for Alastair."
