Two new mutations (1811 + 1G-->C and Y569C) identified in the CFTR gene in patients of Macedonian and Croatian origin.

Two novel CFTR gene mutations were identified in one patient of the Macedonian and Croatian origin, respectively. The two mutations were detected by the method of denaturing gradient gel electrophoresis (a splicing mutation 1811 + 1G-->C) in intron 11, and by single strand conformation polymorphism analysis (a missence mutation Y569C) in exon 12. The mutations were characterized by direct sequencing of amplified DNA, according to Sanger. These two novel mutations were detected as associated with the delta F508 mutation.
