Cystic Fibrosis : An Recessive Disease

Nearly 1 in every 30 Americans are a carrier of the recessive gene that leads to CF (About Cystic Fibrosis, n.d.). Although CF is a life-threatening condition, through the advancement of treatments and care, there has been a steady increase in life expectancy and improvement in the quality of life. The current mean age of survival is now 40. Although that does not seem very high, sixty years ago, a child diagnosed with CF did not survive childhood (About Cystic Fibrosis, n.d.). CF is a complex disease, where the types and severity of symptoms can differ widely from person to person. Symptoms may include fatigue, salty-tasting skin, persistent cough with phlegm, wheezing and shortness of breath, lung infections, and poor growth and weight loss (Cystic Fibrosis Symptoms, Causes & Risk Factors, 2018). Many different factors, such as the age of diagnosis, can affect an individual's health and the course of the

Cystic Fibrosis, also known as CF, is one of the most common life-threatening genetic disorders found in people. Discovered in 1938 by Dr. Dorothy Hansine Andersen, Cystic Fibrosis severely affects two parts of the human body, including the respiratory system and the digestive system. Cystic Fibrosis causes the mucus glands to secrete very thick and sticky mucus. This mucus then clogs the tiny air passages and traps bacteria in the lungs. The thick mucus also stops the release of digestive enzymes in the pancreas from reaching the small intestine. According to Cystic Fibrosis Queensland (2015) more than one million Australians carry the Cystic Fibrosis Gene, with one in every 25 people, often not realising they are carrying the deadly gene.

In 1955, the Cystic Fibrosis Foundation was formed by mothers who were determined to find a cure for their children who were diagnosed with the disease but were given a small life expectancy. As the years went on life expectancy for people diagnosed with CF increased. In 1965, a four-year-old boy was listening to

Cystic Fibrosis is a single gene disease, the Cystic Fibrosis Transmembrane Regulator gene is what causes CF, more than 900 mutations of this single gene has been discovered. Every person inherits two CFTR genes, one from each parent. Children who inherit a faulty CFTR gene from each parent will have CF. Children who inherit one faulty CFTR gene and one normal CFTR

Cystic Fibrosis is a genetic disease which is progressive and limits breathing ability. The lungs and other organs are affected by a thick buildup of mucus. This mucus traps bacteria which leads lung damage, infections, and respiratory failure. The digestive enzymes being released is prevented, affecting the breakdown of food and nutrients being absorbed. ?More than 30,000 children and adults in the United States have Cystic Fibrosis. 70,000 people worldwide.? (Diagnosed With Cystic Fibrosis, Cystic Fibrosis Foundation) Someone who has Cystic Fibrosis have a defective gene from each parent which produces faulty protein. The CFTR gene is the gene that is mutated causing this. The channel that transports chloride in and out of cells is created by instructions that are created by CFTR gene. The regulation of chloride ions and water are prevented creating the thick mucus formed on the passageways of lungs, pancreas, and other organs. Cystic Fibrosis doesn?t cause learning problems are mobility of the person. Babies with this still develop and grow up normally. The average life expectancy is close to 40 years, and has been increasing in the last fifty years thanks to improved care. ?Chronic coughing, recurring chest colds, wheezing, shortness of breath, frequent sinus infections, and allergies that last all year, are the most common symptoms of Cystic Fibrosis.? (Cystic Fibrosis Symptoms) Since this disease is progressive

CF is found in nearly one of every three-thousand live births. But more than eighty percent of the patients are diagnosed by age three. Today, nearly forty percent of the diagnosed inhabitants are at the age of eight-teen or older.

​Cystic fibrosis is a disease that is continually affecting children and adults in the United States. This is an inherited and life-threatening disease which affects many organs in the body. According to the Center for Disease Control, there are an estimated 30,000 people affected by this disease today. There are also approximately 2,500 babies born each year with Cystic fibrosis and unfortunately there are millions of people unaware they even carry the gene for this disease.

Cystic Fibrosis is an inherited disease caused by mutations in a gene on 7th pair of chromosomes. Cystic Fibrosis is a chromosomal abnormality, meaning that one of the 23 pairs of chromosomes are not what they are supposed to be. A person without Cystic Fibrosis has a gene in chromosome 7, which produces a normal and substantial amount of protein called Cystic Fibrosis transmembrane regulator (CFTR), which in turn produces thin and watery mucus. A person with Cystic Fibrosis has a gene in chromosome 7, which produces either abnormal CFTR protein or no CFTR protein at all, which causes the body to produce thick and sticky mucus “A person with CF produces abnormal CFTR protein — or no CFTR protein at all, which causes the body to make thick,

Most of the people diagnosed with CF are usually in the age of 2. The predicted age most people with CF is at age 40. 97-98% of men with CF can not have children because of congenital bilateral absence of the vas deferens. Most of the people with CF, there parents had to be carriers and they gave their children the disease. For example if 2 carriers had a baby the chances of the baby having CF is, ¼ will not have CF, ½ will be a carrier, ¼ will not be carriers or infected. Symptoms of CF vary with each person. Some usually the symptoms are coughing, lung infections, inability to gain weight and, fatty stools. Lung infections are when the bronchial tube gets inflated. It is really rare to get CF it can either last 1 year or it can be for life. If you would want to know if you have it, it requires a medical

Can you imagine struggling and gasping for air for an everyday normal? It all ended for her in the year of 1988. More than 30,000 Americans are diagnosed with it a year. Leslie Adelynn Lacey, a young girl from the small town of Kosciusko, Mississippi, was diagnosed with cystic fibrosis when she was only six months old. Cystic Fibrosis, (CF) is an inherited life-threatening disorder that damages the lungs and digestive system. Mucus builds up in the lungs and blocks the person’s airway, causing this person to have trouble breathing regularly. CF is a genetic disease, meaning that a person does not catch it, it is passed down through DNA. Cystic Fibrosis last with a person his or her entire life time. It occurs throughout the world in every race and ethnicity. There is absolutely no way to prevent a person from contracting CF. Lifespan expectancy is usually 21 for a patient diagnosed. Even though there is no cure for cystic fibrosis, the advancements in learning about the condition, genetics and therapy are a working progress throughout medical experts, and maybe, one day there will be a cure.

Cystic fibrosis, also known as CF, affects over 30,000 children and adults world-wide. CF is a disease in the lungs and digestive system and is still incurable today. It is a disease that causes thick, abnormal mucus in the lungs, nasal polyps, fatigue, and can also damage organs in a person’s body. According to www.cff.org/aboutcf, over 70% of CF patients are diagnosed at two years of age. Cystic fibrosis is one of the most life-threatening diseases in the United States and is very common amongst chronic diseases. Cystic fibrosis is most commonly diagnosed in young children and sometimes adults.

Cystic Fibrosis is a hereditary disease that affects the lungs and the digestive system. It causes thick, sticky mucus in the lungs that causes the lungs to clog and block the pancreas. This disease can be life threatening and the majority of people who are diagnosed are under the age of two. People with cystic fibrosis usually have a shorter than average life span. For a child to inherit the disease both parents must have the gene for the disease. Over 10 million people don’t know that they carry the gene.

This disease is considered as inherited disease mostly among Caucasians, where approximately 1000 new cases are recorded every year. Latinos and American Indians are among the races most likely to acquire CF by genetic characters and less prevalent among African American. Statistics from the health agencies had recorded that there are more than 10 million Americans who have faulty CF gene carriers without them knowing it (Buckingham, 2012). Based on the Changing Epidemiology of Cystic Fibrosis reported by Simmons (1992) in Journal of Pediatrics, he said that from 17,857 patients treated with cystic fibrosis Foundation demonstrated a significant shift in the age distribution of patients. The adult patient population increased and in 1990s the median age range of patients with this disorder is 12.5 years old. Statistics revealed that among the surveyed patients, 90% of those belong to age 12 was diagnosed with CF. Median survival age doubled in later years from age 14 to 28 years. Females are found to have lower median survival age than males. Etiology The main cause of cystic fibrosis is hereditary where a carrier parents may transmit the faulty CFTR to her offspring, whereas if such gene is transferred to the child, the latter has the chance of 25 percent of developing CF. Experts claimed that if the child acquired the faulty CFTR gene from only one parent, say

Cystic fibrosis is a pulmonary disease that affects around 30,000 individuals in the United States and 70,000 individuals worldwide.1 There are about 800 new cases diagnosed each year.1 Understanding of this condition has increased over the years as research has found it to affect more of the body’s systems than initially thought in the late 1900s.2 Due to the common complications it causes, cystic fibrosis is commonly generally classified as a pulmonary condition. However, it can cause dysfunction in many of the body’s systems including the hepatic system, the reproductive system, and the digestive/metabolic system, among others.1

This is a great improvement over survival rate of the 1950s with the life expectancy of 1 year or less for cystic fibrosis patients. Unfortunately, since it is a recessive genetic disease, there are many men and women who are carriers of the disease without actually having the disease themselves. If each parent is a non-affected carrier of cystic fibrosis, there is only a 25 percent chance of having a non-affected, non-carrier child and 50 percent chance of having a child that is a non-affected carrier of cystic fibrosis. Unfortunately there is also a 25 percent chance of having a child affected by cystic fibrosis. This makes prenatal genetic screening very important.
