Postnatal Growth

The charts here were made from our study of 400 A-T patients who had visited the A-T Clinical Center at the Johns Hopkins Hospital between 1995 and 2020. The charts here have centiles calculated specifically for people with the classic form of A-T. Most people with mild A-T will likely plot on the higher end of these centiles. In addition, for easy comparison, we have also added the CDC's 3rd centile line. As an example, an adult with classic A-T plotting at the 50th percentile on the A-T charts would plot at roughly the 3rd percentile on the CDC's charts.

We've also created free online calculators for growth in A-T. You can enter up to 5 ages, and the calculators will return percentile values for A-T and the CDC.

For details about how we made the charts, and for more information on growth in A-T, see our publication, Growth in Ataxia Telangiectasia. The paper will be available on the publisher's website in March 2021, and we will update this page as soon as it is available online.
