What disease is caused by a dominant allele of a single gene?
Huntington's Disease
Sickle cell disease is caused by a?
small change in the DNA of a single gene
Is Huntington's Disease a gene mutation?
No, it's caused by a single point mutation of a gene.
What most mutated genes are which cause human disorders?
A mutated gene is just a gene that doesn't have the correct DNA or alleles.. Depending of the human disorder the gene that is mutated will be different... We use genes throughout our bodies but ALL genes can cause human disorders but there is NO single gene that, when mutated, creates ALL genetic modification...
Cystic fibrosis is an example of?
Cystic fibrosis is an example of an autosomal recessive genetic disease. It is caused by the mutation in the cystic fibrosis trans membrane regulator (CFTR) gene. This gene codes for a chloride ion channel important in creating digestive juices, mucus and sweat. A single mutated copy of the CFTR gene does not lead to disease. There have to be mutations in both alleles in order for the disease to manifest. Therefore, it is labeled as an autosomal recessive genetic disorder.
Does cystic fibrosis have extra chromosomes?
No cystic fibrosis is caused by a mutated CFTR gene.
What give red blood cells the sickle shape?
Sickle shaped red blood cells are caused by Sickle Cell Anaemia. This is a recessive genetic disease, and the sickle shapes of the blood cells are caused by a mutation in the haemoglobin gene. This disease can lead to many health complications, many of which can be fatal. A theory behind the existence of this disease is that the possession of only a single mutated allele can give resistance to malaria in individuals and so is most seen in areas where malaria is most prevalent. Possessing two mutated alleles causes the full disease.
What chromosome is polycystic kidney disease found?
It is a mutated gene called PKD1 located on chromosome 16.
This is caused by a dominant single gene defect and generally does not appear until the individual is 35-45 years of age?
Huntington's Disease.
What is the cause of ichtyosis disease?
Ichthyosis is mainly caused by a gene mutation. Chances of the child developing this skin disorder is 50%. With this mutated gene, the person's skin cells reproduce to quickly to be shed or the skin cells reproduce at a normal rate yet sheds slowly.
What is a changed gene?
mutated
What is the mutated gene of the Charcot-Marie-Tooth disease?
CMT is caused by mutations in genes that produce proteins involved in the structure and function of either the peripheral nerve axon or the myelin sheath. Although different proteins are abnormal in different forms of CMT disease, all of the mutations affect the normal function of the peripheral nerves. The gene mutations in CMT disease are usually inherited.
