    Abstract:
    Total RNA and mRNA were prepared from cystic fibrosis (CF) and control nasal polyps and nasal epithelial cells. Genomic clones from the chromosomal region of the CF locus were screened by northern blots. A representative cDNA library from nasal polyps was cloned in the vector lambda gt10. For the construction of a physical genomic map around the CF locus single gene markers were isolated from metaphase 1:7q2qter chromosomes by laser micro-dissection and subsequent microcloning. A linkage study with the polymorphic markers met-H, met-D, and pJ3.11 was performed in 53 German CF families with at least 2 children. No significant correlation of any haplotype on the CF chromosomes with the clinical severity of the course of the disease could be observed, which provides evidence that cystic fibrosis is genetically homogeneous.
