Hungtington disease is a trinucleotide repeat genetic disorder, in which you have extra repeats of CAG in your gene coding for the hungtin protein. If you have more than 35 repeats you get the phenotype (symptoms), and it shows anticipation, which means that as the disease is passed on from generation to generation the repeats increase, hence the severity of the disease. It is quite rare, but the exact incidence is hard to estimate, because people carrying 30 repeats are asymptomatic. Hope this helps

What a human genetic disorder caused by a dominant gene is?
Huntington disease
Why does huntington disease persist as a degenerative genetic disorder?
Several reasons. Until a few years ago, there WAS no genetic screening possible for HD- only when symptoms developed could the disease be diagnosed. Symptoms typically appeared between 30-40 years of age- AFTER people had already had children. As a result, a new generation of Huntington's patients would be born before the parents knew that THEY had HD.
Is huntingston disease x or y chromosome?
Huntington's disease is a genetic disorder caused by a mutation in the HTT gene located on chromosome 4, not on the X or Y chromosomes. This mutation leads to the production of a faulty form of the protein huntingtin, which causes damage to nerve cells in the brain.
What are three mechanisms that cause allele frequency differences in a population?
Mutation, migration, and genetic drift
Where is Huntington disease found in the body?
Huntington's disease primarily affects the brain. It is a neurodegenerative disorder that causes the progressive breakdown of nerve cells in the brain. Symptoms typically include movement disorders, cognitive decline, and psychiatric disturbances.
Is huntingtons a chromosomal or a genetic disease?
Hungtington's disease is a dominant mutation in the gene that codes for the protein 'Huntington' It only affects a single gene, the remainder of the chromosome is unaffected and therefore it is not a chromosomal abnormality
Is huntington disease contagious?
Huntington's disease is not contagious as it is a genetic disorder. It is passed down from parents.
What is the name of the genetic test for Huntington's disease so my doctor can order it?
The genetic test for Huntington's disease is commonly referred to as the "Huntington's disease genetic test" or "HTT gene testing." This test analyzes the CAG repeat expansion in the HTT gene on chromosome 4. If you're discussing this with your doctor, you can simply refer to it as the Huntington's disease genetic test, and they will know how to proceed with the ordering process.
What are examples of lethal genetic disorders?
This means that you have a genetic disease where as your DNA suppresses certain proteins in your body, thus either 1: giving you a deadly mutation somewhere on the body or 2: killing you I think?
Can you catch huntington's disease?
Nope it's genetic
Is Huntington's a genetic disease?
Yes, autosomal dominant.
Is huntington's disease chromosomal error or a multifactorial trait?
Huntington's disease is primarily caused by a genetic mutation, specifically an expansion of CAG repeats in the HTT gene located on chromosome 4. This mutation leads to the production of a toxic protein that causes neurodegeneration. While there are some environmental factors that may influence the onset and progression of the disease, it is not considered a multifactorial trait in the same way that conditions like heart disease or diabetes are. Thus, Huntington's disease is fundamentally a chromosomal error rather than a multifactorial condition.
How can a person be screened for genetic disorder as huntington's disease?
Several diseases, including Huntington's, have a genetic screening test to identify the presence of the gene that causes Huntington's. Please visit the website for the Huntington's Disease Society of America for some good information.
What is one genetic disease of threat to the nervous system?
ONE is Huntington's Disease.
What is a dominate genetic disease?
Achrondoplasia (dwarfism) is one. Another is Huntington's disease.
What is huntington's disease classified as?
It is a genetic disease. You can only "catch" it by inheriting the gene for it.
Is huntington's disease neutral?
Huntington's disease is not considered neutral; it is a hereditary neurodegenerative disorder caused by a mutation in the HTT gene. This condition leads to progressive motor dysfunction, cognitive decline, and emotional disturbances, significantly impacting the quality of life for affected individuals and their families. The mutation is dominant, meaning that inheriting just one copy can lead to the disease, which raises ethical and social considerations around genetic testing and family planning. Overall, Huntington's disease has profound implications for those affected and is viewed as a serious health concern.
