Emerging Genotype-Phenotype Relationships in Primary Ciliary Dyskinesia

Area of Science:

• Genetics
• Pulmonology
• Rare Diseases

Background:

• Primary ciliary dyskinesia (PCD) is an inherited disorder impacting motile cilia function.
• It leads to significant health problems including organ laterality defects, recurrent sino-pulmonary infections, bronchiectasis, and severe lung disease.
• Clinical presentations of PCD exhibit considerable variability, ranging from mild to severe phenotypes.

Purpose of the Study:

• To explore the evolving understanding of genotype-phenotype relationships in Primary ciliary dyskinesia.
• To highlight the impact of genetic advancements on recognizing diverse PCD manifestations.

Main Methods:

• Review of research over the past twenty years on Primary ciliary dyskinesia.
• Analysis of emerging genotype-phenotype correlations.
• Evaluation of data from increasing availability of genetic panels for PCD.

Main Results:

• Variability in clinical presentations of PCD has been documented over two decades.
• Emerging genotype-phenotype relationships are being redefined.
• Genetic panels are revealing previously unrecognized milder forms of PCD.

Conclusions:

• Understanding of Primary ciliary dyskinesia is continually evolving.
• Genetic testing advancements are crucial for identifying the full spectrum of PCD, including milder phenotypes.
• Refined genotype-phenotype correlations improve diagnosis and management of PCD.
