Immunoblot analysis for laboratory diagnosis of ataxia-telangiectasia: use of Epstein-Barr virus-transformed or phytohemagglutinin-stimulated lymphoblasts for detection of ATM protein.
Ataxia-telangiectasia (A-T) is a genetic disorder characterized by a progressive ataxia, immunodeficiency, neurological abnormalities, hypersensitivity to ionizing radiation, and predisposition to cancer. The gene responsible for A-T (ATM) has been cloned and shown to code for a 350 kDa polypeptide containing 3,056 amino acid residues. Detection of ATM mutations for laboratory diagnosis of A-T is laborious and not practical, unless there are common mutations in a population. We describe here immunoblot analysis for the detection of ATM in seven Japanese A-T patients from five families and in controls using ATM3BA antibody. ATM protein was routinely and clearly detected in Epstein-Barr virus (EBV)-transformed or phytohemagglutinin (PHA)-stimulated lymphoblasts from controls. However, it could not be detected consistently in unstimulated peripheral blood mononuclear cells (PBMCs) from controls. We also detected ATM protein in control fibroblasts, but the background was relatively higher than in control lymphoblasts. ATM protein was not detected or dramatically decreased in EBV-transformed lymphoblasts from all seven patients tested and in fibroblasts from one patient. Immunoblot analysis using EBV-transformed or PHA-stimulated lymphoblasts represents a useful approach for laboratory diagnosis for A-T. The latter is especially preferable since it takes only 3 days to obtain sufficient cells for analysis.
