Abstract

We have constructed a physical map of the chromosomal region containing the cystic fibrosis locus using seven DNA markers and pulsed-field gel electrophoresis methods. The map includes cleavage sites for 8 rare-cutting restriction enzymes and spans over 12 megabases (Mb) of DNA, with one unlinked probe covering an additional 5 Mb. To our knowledge, this is the largest segment of human DNA which has been restriction-mapped to date. We can identify thirteen putative HTF islands spaced at intervals of 0.3-3.2 Mb. The region between loci D7S8 and MET, where the CF gene lies, includes 1.4-1.9 Mb of DNA.
