We describe the cloning and mapping of 20 putative members of the IGLV subgroup 1. These gene segments are contained on 26 phage clones which fall into 7 contigs plus one solitary phage. This represents approximately 240 kilobases (kb) of cloned DNA. Like IGLC gene segments, the IGLV gene segments were found to be oriented proximal to distal on the chromosome, indicating IGL somatic rearrangement is by deletion. The gene segments were placed on a long-range map of the IGL locus, which covers at least 800 kb. Clones were further ordered by pulsed field gel electrophoresis analysis of B-cell lines known to produce IGL-containing immunoglobulins. DNA deletions ranged from 120 to 570 kb.
