KEY FACTS ABOUT ATAXIA TELANGIECTASIA (A-T)

A-T is a rare, degenerative
condition that affects many
different parts of the body
and generally appears in
early childhood 1,2

Symptoms progressively
worsen, leading to full-time
wheelchair use – usually
before the early teens2

A-T occurs in approximately
1 in 300,000 live births.
However, A-T diagnosis can
be delayed or missed due to
its similarities with
other conditions 2,3
