title: Taq I restriction polymorphism of HLA class-I genes, and hybridization with HLA-A and HLA-B specific probes.
abstract: Restriction enzyme site polymorphisms for Taq I endonuclease are examined in a panel of DNAs of HLA-typed individuals and families. Using a full-length DNA probe, 13 polymorphic bands were detected in a total of 31 restriction fragments analyzed. Only one of them (the 3.5-kb polymorphic band) correlated absolutely with serological allele B27, as already established. The A- and B-specific probes recognized only a very small subset (4 for the A probe, and 2 for the B probe) of the DNA fragments which were hybridized with the full-length DNA probe. For each of these two loci, a frequent polymorphism was described, which correlated with serologic haplotypes in several families studied.
