Follow-up testing to identify variants in individuals with a clinical diagnosis of cystic fibrosis (CF)
Identifying genetic variants in individuals with atypical presentations of CF (eg, congenital bilateral absence of the vas deferens or pancreatitis)
Identifying genetic variants in individuals where detection rates by targeted variant analysis are low or unknown for their ancestral background
Identifying patients who may respond to cystic fibrosis transmembrane conductance regulator (CFTR) potentiator therapy
