Abstract

Restriction maps were constructed for the two human 21-hydroxylase genes (21-OHA and 21-OHB) by using DNA from subjects homozygous for a deletion of each gene. Comparing the patterns of these two genes, a KpnI restriction site occurred in the 21-OHA gene in place of a TaqI site in the 21-OHB gene about 1-kb from the 5′ end of the gene, and an extra EcoRI site was located 500 bp 5′ to the common EcoRI site. The DNA of fourteen unrelated normal subjects was digested with nine restriction endonucleases (AccI, BamHI, BglII, EcoRI, HindIII, KpnI, MspI, SacI and TaqI). Restriction fragment length polymorphisms were found with EcoRI, HindIII and AccI that resulted from polymorphic endonuclease sites outside the genes.
