GPs Meet Rare Lung Disorders Task Force factsheet: primary ciliary dyskinesia
Breathe (Sheffield, England)
|August 26, 2015
Summary
Primary ciliary dyskinesia (PCD) is a rare genetic disorder affecting cilia structure and function. This leads to impaired mucus clearance, causing respiratory issues and situs anomalies in many patients.
Area of Science:
- Genetics and Molecular Biology
- Respiratory Medicine
- Developmental Biology
Background:
- Primary ciliary dyskinesia (PCD) is an inherited condition characterized by defective cilia.
- Ciliary dysfunction results in impaired mucociliary clearance, a critical defense mechanism in the airways.
- This leads to chronic respiratory infections and potential long-term lung damage.
Purpose of the Study:
- To describe the genetic basis and clinical manifestations of primary ciliary dyskinesia.
- To elucidate the impact of ciliary abnormalities on mucociliary clearance and respiratory health.
- To highlight the association between PCD and situs anomalies.
Main Methods:
- Review of genetic studies on PCD.
- Analysis of clinical data from patients with PCD.
- Examination of ciliary structure and function in affected individuals.
Main Results:
- PCD is an autosomal recessive disorder stemming from structural and functional ciliary defects.
- Impaired mucociliary clearance is a hallmark, leading to diverse respiratory symptoms.
- Situs anomalies occur in approximately 50% of individuals diagnosed with PCD.
Conclusions:
- Primary ciliary dyskinesia significantly impacts respiratory health due to impaired mucociliary clearance.
- Genetic defects in cilia underlie this condition, often presenting with situs inversus or other abnormalities.
- Early diagnosis and management are crucial for mitigating respiratory complications in PCD patients.

The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

2.3K
The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...

1.1K
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

01:20Chronic Obstructive Pulmonary Disease-I: Introduction
4.1K
Chronic Obstructive Pulmonary Disease (COPD) is a long-lasting respiratory condition requiring continuous attention and care. It is a progressive lung disease that leads to breathing challenges due to airflow obstruction. It manifests as persistent respiratory symptoms and restricted airflow resulting from abnormalities in the airways and alveoli, usually due to long-term exposure to harmful particles or gases. COPD mainly consists of two primary conditions: emphysema and chronic bronchitis.

Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.
