Understanding CFTR Functionality: A Comprehensive Review of Tests and Modulator Therapy in Cystic Fibrosis

Area of Science:

• Genetics and Molecular Biology
• Pulmonology and Gastroenterology

Background:

• Cystic fibrosis is an autosomal recessive genetic disorder.
• It stems from mutations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene, impacting ion transport and causing thick mucus.
• Over 2000 CFTR mutations exist, categorized by their functional impact.

Purpose of the Study:

• To comprehensively review and consolidate diagnostic tests for quantifying Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) functionality.
• To discuss recent advancements in CFTR modulator therapy for cystic fibrosis.
• To explore the relevance of CFTR modulator therapy in assessing CFTR function.

Main Methods:

• Literature review and consolidation of existing research on CFTR functionality tests.
• Analysis of current scientific discourse on CFTR modulator therapies.
• Examination of the interplay between therapeutic interventions and diagnostic assessments.

Main Results:

• Identification and categorization of diverse tests crucial for measuring CFTR protein function.
• Detailed overview of emerging CFTR modulator therapies.
• Established the link between modulator therapy efficacy and CFTR function evaluation.

Conclusions:

• Accurate assessment of CFTR functionality is vital for managing cystic fibrosis.
• CFTR modulator therapies represent a significant advancement in treating cystic fibrosis.
• Therapeutic response monitoring provides valuable insights into CFTR protein activity.
