We have demonstrated that the chromosomal breakpoint at 22q11 of a Burkitt lymphoma cell line (PA682) with an 8;22 translocation interrupts the variable region of the lambda light chain locus. In these cells, all of the C lambda and some V lambda sequences translocate to the 8q+ chromosome whereas some V lambda sequences remain on the 22q-. These results indicate that the lambda light chain locus on the long arm of chromosome 22 is oriented such that V lambda is proximal to C lambda.
