Answer

Multiple genetic variants of CF exist, and the risk to patients that have genetic heterozygous mutations remains to be elucidated. However, a reasonable assumption is that patients with CF can be divided into 2 groups: (1) those with classic disease that is readily diagnosed based on clinical and laboratory data and (2) those with less severe disease that manifests later in life and who have ambiguous genetic testing results.
