Ataxia-telangiectasia (A-T) is a rare, genetic, progressive neurological disorder that affects approximately 1 in 40,000 to 1 in 100,000 people worldwide. It is caused by a mutation of the ATM gene, which is responsible for controlling cell division, and results in a wide range of physical, neurological, and immunological symptoms.
The exact number of people in the world with A-T is unknown. However, estimates from the Ataxia-Telangiectasia Children’s Project suggest that it is likely to affect around 1 in 40,000 to 1 in 100,000 people worldwide. A-T is more likely to affect people of Northern European descent, with a prevalence of around 1 in 30,000 in this population.
A-T is a rare disorder, with many cases going undiagnosed or misdiagnosed. As such, it is difficult to accurately estimate the number of people who have A-T worldwide. However, the Ataxia-Telangiectasia Children’s Project is working to raise awareness and increase diagnosis rates of A-T, so that an accurate estimate can be made.
In conclusion, the exact number of people in the world with ataxia-telangiectasia is unknown, but estimates suggest it is likely to affect around 1 in 40,000 to 1 in 100,000 people worldwide.
