However, the nature of the relationship between exposure and carriage of the DP\u03b2E69 genotype has not been well studied. The goal of this study was to determine the relationship between DP\u03b2E69 and exposure in BeS and CBD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Current and former workers (n=181) from a US nuclear weapons production facility, the Y-12 National Security Complex (Oak Ridge, Tennessee, USA), were enrolled in a case\u2013control study including 35 individuals with BeS and 19 with CBD.
