Abstrakt
This study analyses distribution patterns of the ΔF508 mutation of the cystic fibrosis transmembrane conductance regulator gene (CFTR) gene and the cystic fibrosis (CF)-linked marker loci MET, D7S23, D7S399, and D7S8 in a sample of 167 (116 complete) CF families from Bohemia and Moravia (Czechoslovakia). DNA typing was performed by polymerase chain reaction amplification, restriction analysis, and agarose or polyacrylamide gel electrophoresis.
The frequency of the ΔF508 mutation in this sample is 67% and the frequency of the B haplotype is 77.6% on CF chromosomes. Linkage disequilibrium was found between ΔF508 and all markers tested. © 1990 Springer-Verlag.
