cystic fibrosis

Autosomal recessive disorder caused by pathogenic variants in the CFTR gene (cystic fibrosis transmembrane conductance regulator), which encodes a chloride and bicarbonate channel expressed in epithelial cells, and follow the diagnosis criteria. Diagnosis requires evidence of CFTR dysfunction, defined as a sweat chloride concentration of 60 mmol/L or greater, or identification of two CF-causing CFTR pathogenic varia…

What it is

The symptoms and severity of CF can vary. Some people have serious problems from birth. Others have a milder version of the disease that doesn't show up until they are teens or young adults. Sometimes you will have few symptoms, but later you may have more symptoms.

CF is diagnosed through various tests, such as gene, blood, and sweat tests. There is no cure for CF, but treatments have improved greatly in recent years. In the past, most deaths from CF were in children and teenagers. Today, with improved treatments, some people who have CF are living into their forties, fifties, or older. Treatments may include chest physical therapy, nutritional and respiratory therapies, medicines, and exercise.

🧪 Genetic diseases: Genetic diseases are caused by a change in a gene (or a chromosome), often inherited from the parents - such as sickle cell disease, cystic fibrosis and Duchenne muscular dystrophy.

❓ Why it happens

  • A gene is a recipe for a protein. A change in its DNA letters can make the protein faulty or missing.
  • The change can be inherited from one or both parents, or happen for the first time in a child.

🫀 What it does to the body

  • In sickle cell disease, a change in the haemoglobin gene bends red blood cells into a sickle shape; they get stuck in small blood vessels, causing pain, anaemia and organ damage.

🧱 Why it is hard to cure

  • Fixing a gene safely in the right cells of the body is technically difficult.
  • Gene therapies are very expensive, and many genetic diseases are rare, with few patients for trials.

🚀 What research is trying now

  • Gene therapies that add a working copy of a gene.
  • CRISPR gene editing, now approved for sickle cell disease and beta thalassaemia.
  • RNA medicines that work around a faulty gene.
