The Invisible Challenge of Cystic Fibrosis

Cystic fibrosis is a rare, autosomal recessive genetic disorder caused by mutations in the CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) gene, located on one of the 22 pairs of non-sex chromosomes. An affected child inherits two mutated copies of the gene, one from each parent, who possess only a single defective copy and are asymptomatic “healthy carriers”.
