In 20 Italian families with cystic fibrosis (CF), restriction fragment length polymorphisms were detected by five linked markers; a strong linkage disequilibrium is observed between the haplotype B (alleles 2/1 with respect to KM19/XV2c) and CF. The frequency of the delta F508 deletion in CF chromosomes of this sample is 50%. A significant correlation is found between the absence of the delta F508 mutation and pancreatic sufficiency.

Abstract
In 20 Italian families with cystic fibrosis (CF), restriction fragment length polymorphisms were detected by five linked markers; a strong linkage disequilibrium is observed between the haplotype B (alleles 2/1 with respect to KM19/XV2c) and CF. The frequency of the delta F508 deletion in CF chromosomes of this sample is 50%. A significant correlation is found between the absence of the delta F508 mutation and pancreatic sufficiency.
