What is Ataxia Telangiectasia?

What is Ataxia Telangiectasia?

  • Ataxia Telangiectasia: A rare inherited childhood disorder involving progressive degeneration of the nervous system.
  • Ataxia Telangiectasia: Rare hereditary disease characterized by extreme sensitivity to ionizing radiation or radiomimetic drugs because of a defect in DNA repair. AT heterozygosity is estimated to occur in more than 2% of the U.S. population; heterozygotes exhibit increased radiation sensitivity and are at increased risk for several types of cancer. The normal version of the gene that is defective in AT appears to activate the p53-dependent response to DNA damage.
