Webity to CFTR mutations, non-CFTR gene modifiers and environmental factors. For example, specific CFTR gene mutations strongly affect pancreatic function (pheno-type) 57, but environmental and other non-genetic factors have a greater influence on the pulmonary phenotype.

In addition, the composition of the vATPase complex on the SVs is unclear. Here, we summarize the key features of vATPase found on SVs, and propose a model of how vATPase activity is regulated during the SV cycle.
