Insights
Irish newborns have a 1 in 1461 incidence of cystic fibrosis (CF). This study details common and rare CF gene mutation frequencies in Ireland, aiding genetic screening strategies.
Area of Science:
- Medical Genetics
- Population Genetics
Background:
- Cystic Fibrosis (CF) affects 1 in 1461 Irish newborns.
- Current CF screening in Ireland relies on clinical suspicion or family history.
- Neonate CF genetic testing is not standard practice.
Purpose of the Study:
- To determine the frequencies of common and rare cystic fibrosis mutations in the Irish population.
- To identify potentially important CF-related polymorphisms in Irish individuals.
Main Methods:
- Analysis of CF gene mutations from samples across western, mid-western, and southern Ireland.
- Identification of common and rarer CF mutations.
- Detection of various polymorphisms within the CF gene.
Main Results:
- Frequencies of prevalent CF mutations in the Irish population were established.
- Several rarer CF mutations were identified in CF patients.
- Functionally and phenotypically significant polymorphisms were detected.
Conclusions:
- Understanding CF mutation frequencies is crucial for developing targeted genetic screening programs in Ireland.
- Identification of specific mutations and polymorphisms can inform personalized CF care and research.
Abstract:
The incidence of cystic fibrosis (CF) at birth in Ireland is 1/1461. Neonate CF genetic testing is not routinely performed in Ireland. Currently, screening is only carried out where there is clinical evidence or a family history to suggest disease. Here we report the frequencies of common CF mutations occurring in an Irish population composed of samples collected from western, mid-western and southern regions of Ireland. Rarer CF mutations were also identified in a selected number of CF patients. In addition, a number of polymorphisms were identified, some of which are reported to be functionally and phenotypically important.
