What is AT?

Ataxia Telangiectasia or AT, is a rare and complex genetic disorder, affecting a number of different systems within the body. It gives increasing physical disability, while deficiencies in the immune system can lead to frequent colds and infections and the gradual emergence of lung problems. There is an increased risk of cancers, particularly leukaemia and lymphoma, while sensitivity to radiation means that radio-therapy should be avoided and x-rays kept to a minimum.

What causes AT?

AT is caused by a defect, known as a ‘mutation’, on a particular gene, known as the ATM gene. A child born with mutations on both copies of the ATM gene cannot produce a protein, called the ATM protein, which is important in many processes in the body’s cells. Some cells are particularly sensitive to this lack of ATM, and either don’t work properly or die off. This gives rise to the various symptoms of AT.

You can make a difference

Every fundraising activity, and every donation, no matter how big or small, will make a difference to the lives of the people living with AT. With your help we can continue to raise awareness, be there with emotional and practical support for families, commission more medical research and provide a lifeline for everyone affected by AT. Just £5 pays for an Information Pack for a family with a new diagnosis of AT. £5,000 could fund a researcher for a month working on an AT research project.
