immune system
abnormal immunoglobulin light chain V-J recombination ( J:143876 )
• mice were bred to carry the two mutant alleles in trans
• a 2:1 skew in favor of expression of the Igk-Ctm1(IGKC)Mnz allele among immature and mature B cells suggests the CD4 knock-in allele causes a recombination defect
