Abstract: Search for the F-503 deletion in the cystic fibrosis (CF) locus in patients with different forms of this disease has been carried out using polymerase chain reaction followed by gel-electrophoretic characterization of the amplified fragments. This mutation is shown to be associated preferentially with pancreatic insufficiency as the main trait of CF phenotype < (45% homozygotes and 30% heterozygotes) in F-508 among CF patients with pancreatic disorder). On the other hand, in CF patients with pancreatic sufficiency this mutation was detected rarely and only in the heterozygous state (20% patients).
