WHAT IS A-T? A-T (Ataxia-Telangiectasia) is a rare, genetic and degenerative childhood disease that affects multiple systems of the body. Those affected with A-T lack the ATM gene, a gene that contains the instructions to make the A-T protein. The A-T protein controls the rate in which cells grow, divide and repair themselves. It also plays a vital role in regulating the immune and nervous systems.
