The A-T Children’s Project, founded in 1993, funds scientific research aimed at finding a cure and improving the lives of all children with ataxia telangiectasia. According to a statement, "Ataxia-telangiectasia, or A-T, is a fatal genetic disease that affects children at a very early age. This progressive, degenerative disease affects a startling variety of body systems. Children with A-T appear normal at birth, and the first signs of the disease usually appear during the second year of life. They are usually wheelchair-bound by the time they are eight or nine and rarely survive beyond their teens."
