Retrospective study of the cystic fibrosis transmembrane conductance regulator (CFTR) gene mutations in Guthrie cards from a large cohort of neonatal screening for cystic fibrosis

The cystic fibrosis transmembrane conductance regulator (CFTR) gene encodes a cAMP-activated chloride channel, and in individuals with both alleles of the gene mutated, symptoms of CF disease are manifest. Wit...
