Analysis of mice transgenic for immunoglobulin genes should allow definition of the cis-acting DNA sequences required to target somatic mutation to antibody V genes. We have looked for mutations in a chimeric kappa transgene encoding a V region specific for the hapten 2-phenyloxazolone (phOx) linked to a rat C kappa gene. Two independent lines of transgenic mice were hyperimmunized with phOx and splenic hybridomas established. In B cells that had been selected by antigen and which used mouse anti-phOx genes, the endogenous sequences were found to be mutated whereas the transgene remained unchanged. These results suggest either that (a) if the transgene is a "passenger" gene expressed at a low level, transgene mutation is a rare event, or that (b) sequences far from the kappa coding region are necessary to direct somatic mutation.
