The ATM gene (mutated in the disease ataxia telangiectasia) activates the p53 tumor suppressor protein in response to DNA damage, explaining the higher incidence of cancer in AT patients.
Using a polymerase chain reaction single strand conformation polymorphism (PCR-SSCP) assay, which amplifies individually all coding exons of the ATM gene deficient ataxia-telangiectasia (A-T), we ...
