A single abnormal gene produces HD. In 1993, scientists finally isolated the HD (Huntington's Chorea) gene on chromosome 4.

What is the Mode of inheritance hemophilia?
Transmitted by a dominant gene. If that gene is inherited from either parent, the offspring will develop HD. If the gene is NOT inherited, then the offspring will not have HD- AND cannot pass the gene to their offspring.
Why can not people Carry huntingtons disease?
HD is transmitted by a Dominant gene. If you have HD, your childen have a 50-50 chance of developing HD. However, if you do NOT have HD, there is no gene to pass on to your children- so you cannot be a "carrier" of HD.
Can 2 people with Huntington's Disease produce an offspring who does not have Huntington's disease?
Unfortunately, no. Huntington's is carried on a dominant gene. One parent HD, one non-HD, you have a 50-50 chance of not inheriting that gene. But two parents that are HD, you will inherit the gene from one parent or the other.
What are the possible genotypes of parents with tay sachs disease?
50-50. Each parent contributes one pair of genes to their offspring. HD is carried on a Dominant gene. If your father has HD, you may inherit the recessive gene (No HD) or the dominant gene (HD). Odds are exactly even.
Can a person be a carrier of huntingtons disease and not show any symptoms?
Since HD is transmitted by a dominant gene, there are no "carriers", such as in sickle cell anemia. If you have HD, you can pass it along to your children. If you do not have HD, it cannot be passed on.
How do people get Huntington's Disease?
HD is a genetic disease- you do not "catch it" from anyone. But is is inherited from a parent, just as you inherit hair color. One of the parents has a defective gene, which causes them to develop HD. If one of their children inherits that gene, they will also develop HD. However, if they do NOT inherit that gene, they cannot develop HD, and cannot pss it to their children.
What is the ticker symbol for genome therapeutics?
GENE
How many many parents have to have the allele for huntingtons to affect there children?
Either parent. Since HD is carried on a dominant gene, if the gene is inherited from either parent, the offspring will develop HD.
Is Huntingtons Disease a recessive gene?
Unfortunately, HD is carried on a dominant gene. If one parent has the gene for HD, and the other does not, the offspring has a 50/50 chance of developing HD. However, if you do NOT inherit the gene for HD, you cannot be a "carrier" of HD. The Huntingtons Disease Society of America has more information at their website. You may also contact me through my message board if you need additional information.
Will a person with huntington's disease pass the disease to his offspring?
Maybe. Huntington's IS an inherited disease. It is carried on a Dominant gene. That means if one parent has the HD gene, and the other parent does not, then the odds are 50-50 that any one child born to that couple COULD inherit that gene, which will result in their developing HD. However, if you do NOT inherit that gene- it stops there. Unlike some genetic diseases, you cannot be a carrier of HD if you do not have it.
What is the percentage of people in the world have Huntington's disease?
Becasue HD is carried on a dominant gene. Unlike recessive gene diseases, where you would have to inherit the gene from BOTH parents, with a dominant gene disorder- well, you will inherit one of two genes from the parent with HD. One carries HD, the other does not. Odds are 1 out of two, or 50%. For each child born to that parent.
In chatspeak what does HD mean?
