About Ataxia-telangiectasia


Ataxia-telangiectasia, or A-T, is a rare genetic disease that attacks children, causing progressive loss of muscle control, immune system problems, and a high rate of cancer.

Diagnosing A-T

Clinic presentation, laboratory markers, and possible symptoms of A-T. Links to information in languages other than English.

A-T Family Database Registration

We would like to keep in touch with all A-T families so that we can help. From time to time, we reach out with important information about A-T or announcements about clinical studies and trials to help further research.

Caring for People with A-T

Find a 16-page handbook covering topics including neurology, managing lung health, immunology, vaccine schedules, cancer, and school recommendations. Since A-T is a rare disease, it can be difficult to find comprehensive information on how to best manage an A-T patient's health. The A-T Children's Project has been funding specialized clinical evaluations for A-T since 1995, and much of the information found here is a result of the hundreds of families who have been a part of this effort.
