Background: Cancer in patients with cystic fibrosis (CF), the most common genetic disorder in Caucasians, has been a rare event. However, more patients now reach adulthood, and more patients undergo organ transplantation-factors associated with an increased cancer risk. Our aim was to assess the risk of cancer in nontransplanted and transplanted CF patients.

Objective: To investigate the impact of early diagnosis on pulmonary function in a large cohort of children with cystic fibrosis (CF).

Study Design: CF cases identified from the CF Foundation National Patient Registry and diagnosed between 1982 and 1990 were categorized as: early asymptomatic diagnosis (EAD; n = 157), early symptomatic diagnosis (ESD; n = 227), later asymptomatic diagnosis (LAD; n = 161), and later symptomatic diagnosis (LSD; n = 3080). Early CF diagnosis was diagnosis before 6 weeks of age; later diagnosis was diagnosis at 6 weeks to 36 months of age, inclusive.

Purpose: To update estimates of individual and cumulative cystic fibrosis (CF) mutation frequencies in non-Hispanic Caucasians for the prenatal screening panel recommended by American College of Medical Genetics and to determine the impact on screening performance.

Methods: Two data sources were used. In the first (CF Genetic Analysis Consortium), our re-analysis was restricted to North American studies.
