Distribution of 9 common mutations in the CFTR gene in Slovak cystic fibrosis patients.

Abstract

The distribution of 9 known mutations in the CFTR gene were studied in 234 CF chromosomes originating from 117 unrelated cystic fibrosis (CF) patients from Slovakia, a population which is geographically situated at the borders between Western and Eastern Europe, and Northern and Southern Europe. The following 7 mutations were identified in this sample: delta F508 (59.4%), G542X (5.56%), R553X (3.42%), N1303K (2.99%), R347P (1.71%), W1282X (0.85%), and 3849 + 10 kb (0.43%). These mutations represent 74.36% of all CF mutations, providing a good basis for direct DNA-based diagnosis of CF in Slovakia.
