Which inherited disease is caused by faulty ion channels?
Cystic fibrosis is one.
What causes huningtons disease?
Huntingtons disease is a genetic/inherited diesease. It is caused by a faulty allele (a dominant one), which can be inherited by parents. Spontanoius mutations may also occur which would cause the faulty gene and therefore huntingtons disorder.
What is phenylketonurice?
The Answer is: an inherited disease due to faulty metabolism of phenylalanine, characterized by phenylketones in the urine and usually first noted by signs of mental retardation in infancy.
Why are some characteristics inherited and others are caused by the environment?
Some characteristics are caused by the environment, some by inherited factors, while some are caused by both environment and inherited factors.Male mammals carry XY sex chromosomes - female mammals carry XX chromosomes. Inherited disorders are caused by faulty genes on these chromosomes.Different versions of a gene are called alleles, and these alleles can be dominant or recessive. Genetic diagrams can show the possible outcomes of a particular cross.
What causes Schilder's disease symptoms?
Symptoms of the disease are caused by widespread patches of demyelination throughout the brain and spinal cord, resulting in slowed, faulty nervous transmission.
How cancer this affect perdicting cancer in affected families?
There are many different causes of cancer and having a certain gene will not definitely mean that you develop the disease. Only around 5-10 per cent of cancers are thought to be caused by faulty inherited genes. read more about cancer at http://cancerlinks.blogspot.com/
Which of the following is the first step in gene therapy?
Identifying the faulty Gene. Identifying the faulty Gene that causes the disease.
Is huntington disease due to heredity?
Yes, Huntington's Disease is a hereditary condition. Huntington's is caused by a faulty gene, so if, say, the mother of a son has it, the son has a 50% chance of getting it too.
Is Huntington's Disease a gene mutation?
No, it's caused by a single point mutation of a gene.
How are the scientists in the Field in genetics trying to help people with genetic disorders?
They can cure inherited genetic diseases by taking the faulty gene out of the person's DNA, and replacing the faulty gene with a healthy gene. This way the person is not only cured from the disease, but any future generations in that person's family won't be affected either, because the faulty gene will have been removed altogether.
What causes inherited condition?
A faulty gene handed down from one or both of the parents.
Why is it that two normal parents could have a child with pku?
PKU, phenolketonuria, is a genetic disease caused by a recessive gene. So, a person with one normal and one faulty gene for this characteristic will not have the disease, you have to have two faulty genes to have the disease. If two people who each have one gene for PKU have a child, that child can inherit the gene from each parent and therefore will have two copies, causing the recessive trait to manifest.
