Molecular basis of cystic fibrosis in the Republic of Macedonia.

Eighty-three cystic fibrosis (CF) patients and their families, belonging to various ethnic groups living in the Republic of Macedonia were studied for molecular defects in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, and for the associated extragenic marker loci XV-2c and KM19. The DNA methodology used included characterization of CFTR mutations in 19 exons (and flanking sequences) of the gene and analysis of distribution of the XV-2c/KM19 haplotypes among normal (N) and CF chromosomes by polymerase chain reaction (PCR) amplification followed by dot blot hybridization, restriction digestion, single-strand conformational polymorphism, constant denaturing gel electrophoresis, denaturing gradient gel electrophoresis, and sequencing. We identified 58.

A new polymorphism in exon 7 of the cystic fibrosis transmembrane regulator (CFTR) gene.

Here we describe a new polymorphism, located in exon 7 of the cystic fibrosis transmembrane regulator (CFTR) gene at nucleotide position 1104 (C-->G), detected by a single-strand conformational polymorphism (SSCP) analysis.

delta F508 frequency and associated haplotypes near the cystic fibrosis locus in the Yugoslav population.

Chromosomes from 19 unrelated Southern Yugoslav families in which cystic fibrosis (CF) occurs were analysed for the presence of the delta F508 mutation, using polymerase chain reaction amplification followed by dot blot and polyacrylamide gel analysis. Of the 38 CF chromosomes, 15 (39.5%) carry the delta F508 deletion.
