c.3844T>G , p.Trp1282Gly (CFTR1) D , The mutation W1282G was detected by DGGE and direct sequencing in a patient from Brazil (Caucasian origin), she carries [delta]F508 on the other chromosome and he presents PI and mild lung disease. c.3844T>C , p.Trp1282Arg (CFTR1) ? , In exon 20 we have found one Russian patient with the mutation T3976C. This mutation creates an AciI site. This enzyme also cuts DNA with the A4002G polymorphism. The two can be distinguished based on the size of the products. c.3846G>T , p.Trp1282Cys (CFTR1) ? , Found by DGGE and DNA sequencing. (CF patient, genotype [delta]F508/W1282C) |

Newborn screening for cystic fibrosis: Polish 4 years' experience with CFTR sequencing strategy.
Eur J Hum Genet. 2012 Aug 15. doi: 10.1038/ejhg.2012.180., [PMID:22892530]
Abstract [show]
Newborn screening for cystic fibrosis (NBS CF) in Poland was started in September 2006. Summary from 4 years' experience is presented in this study. The immunoreactive trypsin/DNA sequencing strategy was implemented. The group of 1 212 487 newborns were screened for cystic fibrosis during the programme. We identified a total of 221 CF cases during this period, including, 4 CF cases were reported to be omitted by NBS CF. Disease incidence in Poland based on the programme results was estimated as 1/4394 and carrier frequency as 1/33. The frequency of the F508del was similar (62%) to population data previously reported. This strategy allowed us to identify 29 affected infants with rare genotypes. The frequency of some mutations (eg, 2184insA, K710X) was assessed in Poland for the first time. Thus, sequencing assay seems to be accurate method for screening programme using blood spots in the Polish population.European Journal of Human Genetics advance online publication, 15 August 2012; doi:10.1038/ejhg.2012.180.

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.
