CFTR and cystic fibrosis: A number of reports on CF screening recently have been published: a cost-effectiveness analysis that compared four CF neonatal screening strategies with or without DNA testing to assess the value of combining cost effectiveness and ethics evaluation in health policy development (NBS laboratory protocol) [776]; studies analyzing inconclusive diagnoses after a screen-positive test (CFTR issues) including gene-sequencing and genetic counseling [777,778,779,780]; and review of a centralized tracking process to optimize the CF screening program [781].
