Comigration analysis with probes for the IG heavy chain gene (IGH), kappa-chain gene (IG kappa) and lambda-chain gene (IG lambda), demonstrated a 5'-BCL2/IGH junction at the JH region in four patients with NHL derived from follicular center B cell.     ///    Molecular cloning of a 5'-BCL2/IGH junction demonstrated recombination of the two affected genes in divergent orientation.
