Calculator for weight in children with ataxia-telangiectasia

This calculator gives syndrome-specific percentile and a standard deviation scores for people with ataxia-telangiectasia (A-T). Data was gathered from records at the Johns Hopkins A-T Clinical Center, Baltimore, and is based on measurements from 400 people with the classic form of A-T. (1) All results are compared with the CDC's growth data for the general population.

Important: our A-T weight data goes to age 23.0, but the CDC data only goes to age 20.0. To help make rough comparisons for ages 20-23, we've used the CDC's values for age 20.0 for ages 20.1 to 23.0. Bear in mind that CDC percentiles for ages older than 20.0 will be slightly inaccurate.

We also have a height calculator and a BMI calculator for A-T.

Please enter the following information about yourself or your child. We don't see, record, or keep any information you enter here.
