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.

What a human genetic disorder caused by a dominant gene is?
Huntington disease
What is a Co-dominant alleles disorder?
One example is Huntington's Disease. With a recessive genetic disorder, to develop the disorder, you must inherit the gene from BOTH parents (odds, 1 in 4). With a dominant gene disorder, if you inherit the gene from ONE parent, you will develop that disorder (odds- 1 in 2).
What is a dominate disorder that results in gradual deterioration of brain tissue in middle age?
Huntington's disease is a dominant genetic disorder that leads to the gradual degeneration of brain cells, particularly in the basal ganglia and cerebral cortex. Symptoms typically appear in middle age and include cognitive decline, motor dysfunction, and psychiatric symptoms. There is currently no cure for Huntington's disease.
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.
An abnormal condition that a person inherits through genes or chromosomes is a?
An abnormal condition that a person inherits through the chromosomes or genes is a genetic disorder.
Is huntington disease contagious?
Huntington's disease is not contagious as it is a genetic disorder. It is passed down from parents.
Is Huntington's disease caused by 3 chromosomes of the 21st pair?
page 314 Huntington's disease is lethal GENETIC DISORDER caused by a rare dominant allele. It's not a chromosonal disease, it is a genetic disorder. D
What a human genetic disorder caused by a dominant gene is?
Huntington disease
What is the dominant genetic disorder that first appears in middle age?
Huntington's Disease
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 a Co-dominant alleles disorder?
One example is Huntington's Disease. With a recessive genetic disorder, to develop the disorder, you must inherit the gene from BOTH parents (odds, 1 in 4). With a dominant gene disorder, if you inherit the gene from ONE parent, you will develop that disorder (odds- 1 in 2).

What is huntingtons disorder?
Huntington's disease is a genetic disorder that causes the progressive breakdown of nerve cells in the brain. It leads to various physical and mental symptoms, including involuntary movements, cognitive impairment, and psychiatric issues. There is currently no cure for Huntington's disease.
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
What is a human genetic disorder caused by a dominant gene is?
One example is Huntington's Disease. Carried on a dominant gene, it causes deterioration of the central nervous system, affecting movement, swallowing, personality, etc.
