[Allele polymorphism of the DNA loci MET, D7S8, D7S23, linked to the cystic fibrosis gene in some populations of the USSR, in high risk families and in cystic fibrosis patients].
RELP analysis of DNA loci MET, D7S8 and D7S23 was carried out in Leningrad population and partially in populations of Moscow, Azerbaijan, Ukraine, Buryatia as well as in individuals from high risk families and in cystic fibrosis (CF) patients by means of blot hybridization and polymerase chain reaction. Allelic polymorphism of all loci studied in these three groups was found to be quite similar to that in the North-Western Europe and in whites of the North America. Linkage disequilibrium of the alleles studied with the CF gene was especially pronounced for alleles of the D7S23 locus and gradually decreases from KM-19 through CS-7 to XV-2c DNA probes. The data witness genetic homogeneity of the CF mutation in European populations of the USSR and its similarity to this mutation in Western Europe. The significance of these data for potential diagnosis of CF and for heterozygous carrier detection is discussed.
