2. The long range DNA organisation of the class II and class III regions in eight HLA homozygous cell lines has been analysed using PFGE. Comparison of the size of the BssHII restriction fragment observed for these cell lines and five individuals possessing one to three C4 genes, shows that the organisation of the C4 genes on each chromosome can be deduced from a single PFGE experiment. Outside of the C4 and 21-OHase loci the class III region shows a highly invariant structure, with no detectable differences in the amount of DNA present. Moreover the class III region is rich in CpG-islands, one of which has been characterised, and contains at least thirteen new genes. However, in the class II region, two differences between common haplotypes have been found. The DRw52-related haplotypes have the same DNA organisation. DR2 haplotypes possess 20-30 kb more DNA in the DRB region. DRw53 haplotypes have 100-130 kb more DNA than DRw52-related haplotypes in the region containing the DRB and DQA genes.
