Understanding thee Complex Relationship Between Cystic Fibrosis and Autoimunite Conditions

Co to je Cystic Fibrosis?

Cystic fibrosis is ingited in an autosomal recessive pattern, meaning that a person mutt inherit a mutated copy of the CFTR gene from both parents to develop the diseaseate. The CFTR protein funktions as an ion channel that transports chloride ions across epitelial membranes. More than 2,000 mutations have been identified, classied into six type based on how they affect CFRTR production, procesing, or funktion.

Clinicians manageming CF patients broud maintain a low attrald for investiting sympations such as unexplicineed joint pain, suggue, skin rashes, or thyroid dysfunktion.
