Yes- in most cases, symptoms depend on your age. You would have the gene all of your life, but symptoms do not usually become apparent until you are older- 30 to 50 yrs old.
It is inherited by a dominant gene.
For a person with the Huntingtons gene the first symptoms usually strike in late middle age at around 50-55. There are people however with the gene who have had first symptoms in their late 80s and some in their early 20s. You have to have the gene to get the disease.
The hunt for the gene was accomplished by the work of many dedicated researchers working cooperatively.
Either parent. Since HD is carried on a dominant gene, if the gene is inherited from either parent, the offspring will develop HD.
Huntingtons disease is a genetic/inherited diesease. It is caused by a faulty allele (a dominant one), which can be inherited by parents. Spontanoius mutations may also occur which would cause the faulty gene and therefore huntingtons disorder.
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.
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.
Huntingtons disease is Autosomal dominant, i.e. a 50% chance of inheritance if one parent has the gene. Where as sickle cell anemia is autosomal recessive. This gives a 25% chance of inheritance if both parents are carriers.
People that MAY have Huntington's can have a genetic test- IF they are positive for HD, they may choose not to have children- and no one will inherit the gene that causes HD.
One example is Huntington's Disease. Carried on a dominant gene, it causes deterioration of the central nervous system, affecting movement, swallowing, personality, etc.
Get Lost - Huntingtons album - was created in 1999-01.
An autosomal genetic disorder is Huntington's disease.
