?
, This mutation was found in a male Turkish patient (first reported Aug 4, 1997). His sweat chloride was 60 meq/l and showed lung disease at age of 26 months. His other CF mutation was later reported to be 406+3T->C (on March 23, 1998).
c.204A>T , p.Lys68Asn (CFTR1) ? , This mutation was detected in a single Turkish CF patient of Syrian origin. The second mutation is yet unknown. The mutation segregates with haplotype C. |

Retrospective analysis of stored dried blood spots from children with cystic fibrosis and matched controls to assess the performance of a proposed newborn screening protocol in Switzerland.
J Cyst Fibros. 2012 Jul;11(4):332-6. doi: 10.1016/j.jcf.2012.01.001. Epub 2012 Feb 1., [PMID:22300503]
Abstract [show]
BACKGROUND: Newborn screening (NBS) for Cystic Fibrosis (CF) has been introduced in many countries, but there is no ideal protocol suitable for all countries. This retrospective study was conducted to evaluate whether the planned two step CF NBS with immunoreactive trypsinogen (IRT) and 7 CFTR mutations would have detected all clinically diagnosed children with CF in Switzerland. METHODS: IRT was measured using AutoDELFIA Neonatal IRT-Kit in stored NBS cards. RESULTS: Between 2006 and 2009, 66 children with CF were reported, 4 of which were excluded for various reasons (born in another country, NBS at 6 months, no informed consent). 98% (61/62) had significantly higher IRT compared to matched control group. There was one false negative IRT result in an asymptomatic child with atypical CF (normal pancreatic function and sweat test). CONCLUSIONS: All children but one with atypical CF would have been detected with the planned two step protocol.
