Ataxia-telangiectasia (AT) is a rare genetic disorder causing neurological issues, blood vessel irregularities, and a weakened immune system, particularly noted in Latin American patients.
A study involving 218 patients revealed that the average age for symptoms and diagnosis is about 1 year and 5 years, respectively, with common recurrent airway infections linked to IgA deficiency.
The study found a mean survival of 24.2 years, with a 20-year survival rate of 52.6%, and higher mortality rates in females and those with low IgG levels, highlighting the importance of assessing immune function in AT patients.
