Cystic fibrosis (CF) is a genetic disorder inherited in an autosomal recessive manner that impairs the normal clearance of mucus from the lungs, which facilitates the colonization and infection of the lungs by bacteria, notably Staphylococcus aureus. CF is a rare genetic disorder that affects mostly the lungs, but also the pancreas, liver, kidneys, and intestine. The hallmark feature of CF is the accumulation of thick mucus in different organs. Long-term issues include difficulty breathing and coughing up mucus as a result of frequent lung infections. Other signs and symptoms may include sinus infections, poor growth, fatty stool, clubbing of the fingers and toes, and infertility in most males. Different people may have different degrees of symptoms.
Bronchiectasis is a disease in which there is permanent enlargement of parts of the airways of the lung. Symptoms typically include a chronic cough with mucus production. Other symptoms include shortness of breath, coughing up blood, and chest pain. Wheezing and nail clubbing may also occur. Those with the disease often get lung infections.
In genetics, a nonsense mutation is a point mutation in a sequence of DNA that results in a nonsense codon, or a premature stop codon in the transcribed mRNA, and leads to a truncated, incomplete, and possibly nonfunctional protein product. Nonsense mutations are not always harmful; the functional effect of a nonsense mutation depends on many aspects, such as the location of the stop codon within the coding DNA. For example, the effect of a nonsense mutation depends on the proximity of the nonsense mutation to the original stop codon, and the degree to which functional subdomains of the protein are affected. As nonsense mutations leads to premature termination of polypeptide chains; they are also called chain termination mutations.
Cystic fibrosis transmembrane conductance regulator (CFTR) is a membrane protein and anion channel in vertebrates that is encoded by the CFTR gene.
The Cystic Fibrosis Trust is a UK-based national charity founded in 1964, dealing with all aspects of cystic fibrosis (CF). It funds research to treat and cure CF and aims to ensure appropriate clinical care and support for people with cystic fibrosis.
Vertex Pharmaceuticals Incorporated is an American biopharmaceutical company based in Boston, Massachusetts. It was one of the first biotech firms to use an explicit strategy of rational drug design rather than combinatorial chemistry. It maintains headquarters in Boston, Massachusetts, and three research facilities, in San Diego, California, and Milton Park, Oxfordshire, England.
Dorothy Hansine Andersen was the American physician and researcher who first identified and named cystic fibrosis. During her almost thirty year tenure at Babies Hospital of Columbia-Presbyterian Medical Center, Andersen not only identified CF and its inheritance through a recessive gene, she was also at the forefront of developing diagnostic tests and life-extending treatments for the disease. Andersen was also active in researching other diseases that are diagnosed in children. She was the first to describe Glycogen storage disease type IV, which, in recognition of her contributions, became known as Andersen's Disease. Her research on heart malformations informed the development of open heart surgery and the training of new surgeons.
Allergic bronchopulmonary aspergillosis (ABPA) is a condition characterised by an exaggerated response of the immune system to the fungus Aspergillus. It occurs most often in people with asthma or cystic fibrosis. Aspergillus spores are ubiquitous in soil and are commonly found in the sputum of healthy individuals. A. fumigatus is responsible for a spectrum of lung diseases known as aspergilloses.
The Cystic Fibrosis Foundation (CFF) is a 501(c)(3) non-profit organization in the United States established to provide the means to cure cystic fibrosis (CF) and ensure that those living with CF live long and productive lives. The Foundation provides information about cystic fibrosis and finances CF research that aims to improve the quality of life for people with the disease. The Foundation also engages in legislative lobbying for cystic fibrosis.
Venture philanthropy is a type of impact investment that takes concepts and techniques from venture capital finance and business management and applies them to achieving philanthropic goals. The term was first used in 1969 by John D. Rockefeller III to describe an imaginative and risk-taking approach to philanthropy that may be undertaken by charitable organizations.
Ataluren, sold under the brand name Translarna, is a medication for the treatment of Duchenne muscular dystrophy. It was designed by PTC Therapeutics.
Ivacaftor is a medication used to treat cystic fibrosis in people with certain mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, who account for 4–5% cases of cystic fibrosis. It is also included in combination medications, lumacaftor/ivacaftor, tezacaftor/ivacaftor, and elexacaftor/tezacaftor/ivacaftor which are used to treat people with cystic fibrosis.
Lumacaftor/ivacaftor, sold under the brand name Orkambi among others, is a combination of lumacaftor and ivacaftor used to treat people with cystic fibrosis who have two copies of the F508del mutation. It is unclear if it is useful in cystic fibrosis due to other causes. It is taken by mouth.
Dr. John Engelhardt is the director at the University of Iowa Center for Gene Therapy of Cystic Fibrosis, as well as the head of the department of anatomy and cell biology. He is a well known scientist and inventor who created the first cloned ferret and has made huge strides in finding the cure for cystic fibrosis.
Jane Carolyn Davies is a British physician who is Professor of Paediatric Respirology at Imperial College School of Medicine. She is an Honorary Consultant at the Royal Brompton and Harefield NHS Foundation Trust.
Elexacaftor/tezacaftor/ivacaftor, sold under the brand names Trikafta and Kaftrio, is a fixed-dose combination medication used to treat cystic fibrosis. Elexacaftor/tezacaftor/ivacaftor is composed of a combination of ivacaftor, a chloride channel opener, and elexacaftor and tezacaftor, CFTR modulators.
Johanna Rommens is a Canadian geneticist who was on the research team which identified and cloned the CFTR gene, which when mutated, is responsible for causing cystic fibrosis (CF). She later discovered the gene responsible for Shwachman-Diamond syndrome, a rare genetic disorder that causes pancreatic and hematologic problems. She is a Senior Scientist Emeritus at SickKids Research Institute and a professor in the Department of Molecular Genetics at the University of Toronto.
Batsheva Kerem is an Israeli geneticist who was on the research team that identified and cloned the CFTR gene, which when mutated, is responsible for causing cystic fibrosis (CF). She later established the Israel National Center for CF Genetic Research. She discovered the most prevalent cystic fibrosis-causing mutations among the Israeli population, allowing for the establishment of nationwide genetic screening programs to identify carriers of these mutations and enabling prenatal diagnoses. She researches how some CF mutations prevent CFTR protein production by causing nonsense-mediated decay and abnormal mRNA splicing, and how therapies might be able to counteract those problems. She also studies the role of genetic instability in cancer. She is currently a professor at the Hebrew University.
Underrepresented populations, especially black and hispanic populations with cystic fibrosis are often not successfully diagnosed. This is in part due to the minimal dissemination of existing data on patients from these underrepresented groups. While white populations do appear to experience a higher frequency of cystic fibrosis, other ethnicities are also affected and not always by the same biological mechanisms. Thus, many healthcare and treatment options are less reliable or unavailable to underrepresented populations. This issue affects the level at which public health needs are being met across the world.
