Six children, including a 6-year-old Indian-origin boy, has been denied life-saving treatment from a rare disease due to high costs by UK's state-funded health service. Kirath Mann suffers from DMD, which affects one in 3,500 boys in Britain and leaves many in a wheelchair before their 10th birthday. Kirath and five other boys with the condition even wrote personal letters to British Prime Minister David Cameron in June in a bid to get the drug that could save their lives.
