In 10 patients (3.4% of total; 14.9% of abnormal), two variants in CFTR were identified that were associated with CBAVD and/or mild classical CF; in three of 10, at least one rare variant was detected that is not present in the Elucigene CF‐EU2v1 kit and would not have been identified without sequencing the complete gene. This evidence concerns the gene CFTR and cystic fibrosis.
