✦ Synopsis

Analysis of a sample of 50 unrelated cystic fibrosis (CF) patients and 46 nuclear families from Slovakia (Czechoslovakia) by the polymerase chain reaction and Southern hybridization revealed that the proportion of the delta F508 mutation was 58% in this population, and that the frequency of the B (i.e., KM19/XV2c [1-2]) haplotype was increased in both delta F508 and non-delta F508 CF chromosomes (98% and 46%, respectively). These results support the view that the trans-European gradient of the delta F508 frequency is of a geographical rather than of an ethnic origin, and that in Slavonic populations, there exists an as yet unidentified but frequent CF mutation other than delta F508, associated with the B haplotype.

## Communicated by LapChee Tsui The deltaF508 mutation accounts for about 53% of the molecular defects causing cystic fibrosis (CF) in Italy. The numerous additional mutations detected so far are all relatively rare, and about 30% of CF chromosomes carries unknown mutations in our patients. In ord
