CDKN2B and cancer: When considering all cancer types, pathogenic somatic variants in CDKN2A (identified in 12%.7 of CFTR PV carriers; Sidak‐corrected p = 0.0069) and CDKN2B (identified in 4.2% of CFTR PV carriers; Sidak p = 0.0428) were more common in our cohort of CFTR PV carriers than in the global COSMIC database.
