Received October 29, 1984. Accepted December 19, 1984.
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
and some V
sequences translocate to the 8q+ chromosome whereas some V
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
is proximal to C
.
