We investigated the patterns of DNA rearrangements at loci for Ig JH genes in patients with severe combined immunodeficiency (SCID). Four SCID patients without B cells (B- SCID) and four SCID patients with B cells (B+ SCID) were examined. Bone marrow cells of these patients were transformed with EBV. The majority of the transformed cells from three B- SCID patients had the germline configuration at their JH gene loci. The rearranged fragments from one patient were analyzed extensively. The rearranged regions in all of the fragments had a common structure wherein two fragments derived from the JH-S mu region were connected inversely. The possible presence of rearranged forms of VHDJH and DHQ52JH sequences in bone marrow cells of two B- SCID patients were examined directly by the polymerase chain reaction (PCR) method. In one patient, we found neither a VHDJH sequence nor a DHQ52JH sequence within the range of sensitivity of the PCR method. In another patient, we found a VHDJH sequence at an extremely low level and DHQ52JH sequences at a relatively low level. Either RAG-1 or RAG-2 gene was not expressed in the B- SCID-derived cell lines. B+ SCID patients did not show any abnormalities in terms of VHDJH rearrangements. These results indicate that B- SCID may be caused by defects in factors involved in V(D)J rearrangements.
