Color code: non disease-causing < likely benign < VUS < likely pathogenic < disease-causing

CFTR variants are clustered into five groups (click here for more details about the classification of variants):

CF-causing: when in trans with another CF-causing mutation, will result in CF.
CFTR-RD causing: when in trans with a CF-causing mutation, will result in CFTR-related disorders (CFTR-RD) such as chronic pancreatitis, bronchiectasis, CRS-NP (chronic rhinosinusitis with or without nasal polyposis) or CBAVD (congenital absence of vas deferens), according to Bombieri C et al., 2011.
Varying clinical consequence: when in trans with another CF-causing mutation, can either result in CF or in a CFTR-RD.
Non disease-causing: when in trans with a CF-causing mutation, will not cause CF, nor CFTR-RD.
VUS (Variant of unknown clinical significance): unclassified because of insufficient data.
