A VHgene is located within 95 Kb of the human immunoglobulin heavy chain constant region genes

摘要

AbstractUsing cosmids covering about 117 Kb upstream of the human immunoglobulin chain C, gene, we have identified a potentially functional VH gene, belonging to the VHVI subgroup. This VHVI gene is only about 95 Kb from the Cμgene and is probably the first functional VH segment of the Igh locus. These results illustrate the proximity of the human VH, DHand JHsegments involved in creation of the complete heavy chain genes
