19 To scan for several known mutations simultaneously, a multiple allele specific primer extension (MASPE) method was developed.23 Thirty eight mutations were chosen: 30 of the most common mutations world wide24 and eight mutations of regional interest (394delTT, 3821delT, 2143delT, 2184insA, 3732delA/K1200E, R117C, and I1005R), previously detected in Scandinavia,2 Russia,25 or Germany.19 Fifteen target exons were amplified to get the templates for primer extension.26 Owing to the dense location of the mutation sites in seven exons, both DNA strands were used as templates to avoid overlapping of the extension primers.

Cystic fibrosis: a worldwide analysis of CFTR mutations--correlation with incidence data and application to screening.
Hum Mutat. 2002 Jun;19(6):575-606., [PMID:12007216]
Abstract [show]
Although there have been numerous reports from around the world of mutations in the gene of chromosome 7 known as CFTR (cystic fibrosis transmembrane conductance regulator), little attention has been given to integrating these mutant alleles into a global understanding of the population molecular genetics associated with cystic fibrosis (CF). We determined the distribution of CFTR mutations in as many regions throughout the world as possible in an effort designed to: 1) increase our understanding of ancestry-genotype relationships, 2) compare mutational arrays with disease incidence, and 3) gain insight for decisions regarding screening program enhancement through CFTR multi-mutational analyses. Information on all mutations that have been published since the identification and cloning of the CFTR gene's most common allele, DeltaF508 (or F508del), was reviewed and integrated into a centralized database. The data were then sorted and regional CFTR arrays were determined using mutations that appeared in a given region with a frequency of 0.5% or greater. Final analyses were based on 72,431 CF chromosomes, using data compiled from over 100 original papers, and over 80 regions from around the world, including all nations where CF has been studied using analytical molecular genetics. Initial results confirmed wide mutational heterogeneity throughout the world; however, characterization of the most common mutations across most populations was possible. We also examined CF incidence, DeltaF508 frequency, and regional mutational heterogeneity in a subset of populations. Data for these analyses were filtered for reliability and methodological strength before being incorporated into the final analysis. Statistical assessment of these variables revealed that there is a significant positive correlation between DeltaF508 frequency and the CF incidence levels of regional populations. Regional analyses were also performed to search for trends in the distribution of CFTR mutations across migrant and related populations; this led to clarification of ancestry-genotype patterns that can be used to design CFTR multi-mutation panels for CF screening programs. From comprehensive assessment of these data, we offer recommendations that multiple CFTR alleles should eventually be included to increase the sensitivity of newborn screening programs employing two-tier testing with trypsinogen and DNA analysis.

Genotyping microarray for the detection of more than 200 CFTR mutations in ethnically diverse populations.
J Mol Diagn. 2005 Aug;7(3):375-87., [PMID:16049310]
Abstract [show]
Cystic fibrosis (CF), which is due to mutations in the cystic fibrosis transmembrane conductance regulator gene, is a common life-shortening disease. Although CF occurs with the highest incidence in Caucasians, it also occurs in other ethnicities with variable frequency. Recent national guidelines suggest that all couples contemplating pregnancy should be informed of molecular screening for CF carrier status for purposes of genetic counseling. Commercially available CF carrier screening panels offer a limited panel of mutations, however, making them insufficiently sensitive for certain groups within an ethnically diverse population. This discrepancy is even more pronounced when such carrier screening panels are used for diagnostic purposes. By means of arrayed primer extension technology, we have designed a genotyping microarray with 204 probe sites for CF transmembrane conductance regulator gene mutation detection. The arrayed primer extension array, based on a platform technology for disease detection with multiple applications, is a robust, cost-effective, and easily modifiable assay suitable for CF carrier screening and disease detection.

Molecular characterization of cystic fibrosis: 16 novel mutations identified by analysis of the whole cystic fibrosis conductance transmembrane regulator (CFTR) coding regions and splice site junctions.
Genomics. 1992 Jul;13(3):770-6., [PMID:1379210]
Abstract [show]
The spectrum of cystic fibrosis (CF) mutations was determined in 105 patients by using denaturing gradient gel electrophoresis to screen the entire coding regions and adjacent cystic fibrosis transmembrane conductance regulator (CFTR) gene sequences. The nucleotide substitutions detected included 16 novel mutations, 11 previously described defects, and 11 nucleotide sequence polymorphisms. Among the novel mutations, 6 were of the missense type, 4 were nonsense mutations, 4 were frameshift defects, and 2 affected mRNA splicing. The mutations involved all the CFTR domains, including the R domain. Of the 61 non-delta F508 CF chromosomes studied, mutations were found on 36 (59%), raising the proportion of CF alleles characterized in our patient cohort to 88%. Given the efficacy of the screening method used, the remaining uncharacterized mutations probably lie in DNA sequences outside the regions studied, e.g., upstream-promoter sequences, the large introns, or putative regulatory regions. Our results further document the highly heterogeneous nature of CF mutations and provide the information required for DNA-based genetic testing.
