Abstract
Optimal temperature conditions for the detection of 28 known mutations on 15 exons of the human cystic fibrosis transmembrane conductance regulator gene by single strand conformation polymorphism analysis using the Diagen TGGE Apparatus were established. This procedure was applied to the detection of unknown mutations in 58 non-deltaF508 chromosomes. Three novel mutations,-471del3 (5′ flanking region), 3171insC (exon 17a) and 4700(T)8/9 (3′ non-translated region) of the CFTR gene were found. Mutation 3171insC occured in conjunction with the delta F508 mutation on the other allele of a child presenting with severe pathology. Mutation -471 del3 has so far only been found in one healthy individual and her father, and 4700(T)8/9 is a DNA sequence polymorphism.
