Why can Cystic fibrosis be inherited even if neither parent has the disease?
Cystic Fibrosis is an example of a disease inherited as an autosomal recessive genetic disorder. Both parents of a baby who has Cystic Fibrosis have one abnormal recessive gene and one normal dominant gene and are therefore, Cystic Fibrosis carriers. Carriers are said to be heterozygous because they contain one normal copy of the gene and one abnormal copy. A baby who inherits cystic fibrosis has inherited the abnormal gene from both parents and is therefore said to be homozygous recessive.
What is the Salty Baby disorder?
Perhaps cystic fibrosis?Cystic Fibrosis-- Final answer. CFTR channels malfunction and Chloride cannot exchange with bicarb at the epithelial surfaces exposed to the environment. Chloride then gets stuck outside the environment.
What is the ratio of people with Cystic Fibrosis?
According to the Cystic Fibrosis Trust's website:Cystic Fibrosis (CF) is one of the UK's most common life-threatening inherited diseases.Cystic Fibrosis affects over 9,000 people in the UK.Over two million people in the UK carry the faulty gene that causes Cystic Fibrosis - around 1 in 25 of the population.If two carriers have a child, the baby has a 1 in 4 chance of having Cystic Fibrosis.Cystic Fibrosis affects the internal organs, especially the lungs and digestive system, by clogging them with thick sticky mucus. This makes it hard to breathe and digest food.Each week, five babies are born with Cystic Fibrosis.
What is the inheritance pattern for the cystic fibrosis allele what is the reasoning for this conclusion?
If both parents have the gene, the chances are 25% of having a child with Cystic Fibrosis. The male and females x genes are affected by it and only half of it. So when the parents mate and they are going to have a baby, the chances are 25%
You have cystic fibrosis will your baby have it?
that depends on the father, if he also has CF then yes, if he is a carrier then 50%ish will be, if he is not affected in any way, then no but they will be carrers.
How can you get cystic fibrosis?
For a baby to be born with Cystic Fibrosis, both parents must be carriers of the faulty CF gene. Where both parents carry the faulty gene, each child has a one in four chance of having CF, a two in four chance of being a carrier and a one in four chance of not having any CF genes.
Are women beyond a particular age more likely to give birth to a baby with cystic fibrosis?
Yes but depending on your age and the risk you are willin to take
How do you know if your baby has cystic fibrosis?
Cystic fibrosis can be detected days after birth in several ways: Babies can present with symptoms particular to CF or they can be screened for CF as part of a state/provincial health policy. The 'sweat' test is often used as a determinant of CF.
Is cystic fibrosis geneitc?
Yes it is a genetic disorder. For a baby to be born with Cystic Fibrosis, both parents must be carriers of the faulty CF gene. Where both parents carry the faulty gene, each child has a one in four chance of having CF, a two in four chance of being a carrier and a one in four chance of not having any CF genes.
Is cystic fibrosis a genetic dosorder?
Yes it is. For a baby to be born with Cystic Fibrosis, both parents must be carriers of the faulty CF gene. Where both parents carry the faulty gene, each child has a one in four chance of having CF, a two in four chance of being a carrier and a one in four chance of not having any CF genes.
What's Cystic fibrosis?
Cystic fibrosis is a genetic disorder which affects the lungs and pancreas. It causes the lungs to get clogged with mucus, which in turn makes the lungs a breeding ground for bacteria. In the pancreas, it blocks the pancreas from absorbing enzymes, which makes its victims prone to malnutrition. Often times, they have to take treatments such as lung therapy every day, as well as enzyme supplements on a daily basis. The average life expectancy is 37.Cystic Fibrosis is caused by a defective gene which causes a thick, sticky mucus. It builds up in the lungs and pancreas (the organ that helps to break-down food.) Cystic Fibrosis results in life-threatening lung infections and digestive problems. Symptoms are varied, but the most common are: No bowel movements in first 24 - 48 hours of life (baby!) Stools that are pale or clay colored, foul smelling or float. Infants can have salty tasting skin. Recurrent respiratory infections, such as pneumonia or sinusitis. Coughing/wheezing. Weight loss or can't gain weight normally in childhood. Diarrhea, delayed growth and fatigue.Cystic Fibrosis is the most common fatal genetic disease occurring in about 1 in 30,000 births. The gene must be inherited from both the mother and the father. Children inheriting only one copy of the gene are carriers but do not display symptoms. Average life expectancy for Cystic Fibrosis is approximately 32 years of age. There are many treatments but no cure. People with Cystic Fibrosis are at high risk of developing other conditions such as Cystic Fibrosis related Arthritis and Cystic Fibrosis related Diabetes, Liver failure and ultimately respiratory failure leading to death. Once a person with Cystic Fibrosis loses enough lung function the only other treatment is a lung transplant
How can a child have cystic fibrosis?
Cystic Fibrosis cannot be prevented. It is an inherited disease, so there is no possible way to prevent something inherited. One parent will be a carrier and so will the other parent, therefore resulting in the child having CF.
