Meet the sisters who have both been diagnosed with a one in 3.5-million condition which is slowly turning their bodies to crystal. Three-year-old Emily and her sister Poppy-Mae, 22 months, are among just 2,000 people in the world who have been diagnosed with the devastating disease cystinosis. The incurable condition is a genetic disorder that causes a build-up of the amino-acid cystine in the cells of the body. Over time these compounds crystallise in the cells, forming in the kidneys, the eyes, the thyroid gland and the liver. Without treatment, children with cystinosis are likely to experience complete kidney failure by about age ten. In the past, it was rare for people with cystinosis to survive into adulthood. But while the sisters will most certainly both face kidney transplants in later life, the brave tots are facing their uncertain future together. Mum Jessica Kemp, 25, from Leeds, said: "Basically their bodies are slowly being taken over by the crystals which build up in their cells. "Children with cystinosis don't have the best life expectancies but at least they each know what the other one is going through and they will always have someone around to look after them. "When Poppy-Mae was also diagnosed it was devastating, but now I'm glad in a way that they have each other for comfort."
