THIS is five-year-old Keaton Foale, the amazing one-in-135million schoolboys with a bizarre genetic condition that means he will never eat a full meal. Unlike other children of his age, Keaton has never enjoyed a packet of sweets or crisps - and never will. He has been diagnosed with the incredibly rare Congenital Disorder Glycosylation Type Two, which means he cant eat food normally. He has to be fed through a tube into his stomach that he will need for the rest of his life. His condition, which has baffled doctors around the world, was first discovered when he began refusing his bottled milk at three months old. DM Medics at Sunderland General Hospital found out whenever any food went into his stomach it was instantly rejected. They stapled up the top of his stomach when he was just six months old to stop him being sick in an attempt to save his life. Instead they put in a special feeding tube that delivers a high-calorie milk mixture to his stomach four times a day in 50-minute sessions. Mother Claire Plummer, from Sunderland, Tyne and Wear, became frantic with worry after her son first developed the rare symptoms. Claire, 29, who is a full-time mother to Keaton, Bethany, ten, and Dylan, eight, said very little was known about Keatons rare genetic disorder. She said: 'As his weight plummeted, doctors put Keaton on tube feeds through his nose - but even this didnt stop him vomiting. 'Something had to be done to make sure that he could get the nutrition he so desperately needed. 'Doctors were forced to insert a feeding tube directly into his stomach. 'When tests were carried out using a kind of X-Ray food machine, to find out why Keaton couldnt eat, doctors were stunned. 'The milk was simply stuck in his throat - he couldnt swallow. 'The dribbles of milk that did get past his throat either went to his stomach, making him vomit or ended up in his lungs. 'I was so worried when I first heard about his condition. 'For years the doctors couldnt diagnose what was wrong with him and even now, knowing that he suffers from such a unique condition is little consolation really. 'Doctors still arent sure about all the things that are wrong with my son. 'There are only a few people in the world who actually deal with CDG because it is such a unique condition. Glycosylation Type Two is a genetic disorder, which is not hereditary and can cause a spectrum of disturbing symptom, including cancer and deafness. As well as not being able to eat, Keaton also suffers from internal bleeding on a regular basis and loses several pints of blood every year. Sometimes he bleeds as often as two or three times a week. Keaton was born at just 24 weeks and was just four inches tall - the length of a Biro pen - when he was delivered, but doctors believe this has had no bearing on him developing the condition. In the first year of his life alone, he battled through jaundice, anaemia and blood infections and had laser-eye surgery to stop him going blind. After years of tests and problems he was finally diagnosed with CDG at the age of three-and-a-half. The life expectancy of sufferers varies from 3 months to 60 years. Even now he struggles to get up and down stairs by himself, and has difficulties with his speech. American Dr Hudson Freeze, one of the few experts in the condition, said Keatons was the most unusual case he had encountered. He said: 'With Type Two CDG, which he suffers from, we dont yet know specifically what gene is at fault. 'As yet there is no cure for Type Two and research is ongoing. 'There are only a few people worldwide who suffer from CDG Type Two and Keatons condition is particularly extreme. DM
