Abstract

We describe a patient in whom newborn immunoreactive trypsin screening and mutation analysis suggested a diagnosis of cystic fibrosis; however, the clinical course and sweat test results were not consistent with the diagnosis. Direct sequencing of the patient's genomic DNA showed compound heterozygosity for ΔF508 and F508C, a polymorphism not associated with clinical disease.
