Does cystic fibrosis cause immune deficiency?

No: Cystic fibrosis is not and does not lead to immune deficiency. It causes the pulmonary secretions to be excessively sticky which leads to recurrent/persistent lung and sinus infections.

No: Cystic fibrosis does lead to more problems with development of disease but not due to immune dysfunction.

Yes: CF trans membrane regulator protein regulates mucosal immunity and the ability to clear infections from the lung, It may be considered an immune deficiency since the CF transmembrane regulator protein is not working as it should.
