One example of a disease caused by a single mutated gene is cystic fibrosis. This genetic disorder is caused by mutations in the CFTR gene, which leads to the production of thick, sticky mucus that can clog the lungs and obstruct the pancreas. Symptoms often include respiratory issues, digestive problems, and increased susceptibility to infections. Other examples include sickle cell anemia and Huntington's disease.
What else can I help you with?
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.
Is huntington disease a autosomal dominant disorder?
Yes, Huntington's disease is an autosomal dominant disorder caused by a mutation in the HTT gene on chromosome 4. An affected individual has a 50% chance of passing on the mutated gene to each of their children.
If a boy inherits a disease that is autosomal recessive he inherited it from his mother?
If a boy inherits an autosomal recessive disease, he would have inherited one copy of the mutated gene from each of his parents. The mother is a carrier, meaning she has one copy of the mutated gene but does not show symptoms of the disease. When both parents are carriers, there is a 25% chance with each pregnancy that the child will inherit two copies of the mutated gene and have the disease.
Why is Huntington's disease dominant in inheritance patterns?
Huntington's disease is dominant in inheritance patterns because only one copy of the mutated gene is needed to develop the disease. This means that if a person inherits the mutated gene from just one parent, they will likely develop Huntington's disease.
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.
Why are most mutations in eukaryotes recessive?
Most mutations in eukaryotes are recessive because they typically involve changes in a single gene, and the presence of a normal copy of the gene can often mask the effects of the mutated gene. This means that the mutated gene is only expressed when both copies of the gene are mutated, resulting in a recessive trait.
Is Canavan disease inherited?
Yes, Canavan disease is an inherited genetic disorder caused by mutations in the ASPA gene. It is inherited in an autosomal recessive pattern, meaning that an individual must inherit two copies of the mutated gene (one from each parent) to develop the disease.
Which of the following is an example of an autosomal dominant disease A Huntington's disease and neurofibromatosis type 1 or B Alzheimer's Disease and Heart Disease?
A. Huntington's disease and neurofibromatosis type 1 are examples of autosomal dominant diseases. These conditions are caused by a single copy of a mutated gene on an autosome (non-sex chromosome) and can be passed down from one affected parent to their offspring with a 50% chance of inheritance.
Is Huntington's disease caused by a gene mutation or a chromosomal mutation?
Huntington's disease is caused by a gene mutation, specifically in the HTT gene on chromosome 4.
