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.
Yes, by genetic screening. See the website of the Huntington's Disease Society of America for more information.
No. HD is carried on a dominant gene. If you do not inherit that gene, you will not have HD, and cannot transmit the gene to your children- you do not have it to transmit.
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.
Asymptomatic carrier, a person or organism infected with an infectious disease agent, but displaying no symptomsGenetic carrier, a person or organism that has inherited a genetic trait or mutation, but displaying no symptoms
That person may be asymptomatic and considered to be a carrier.
Prior to onset of symptoms- not really. Symptoms can be similar to an intoxicated person- slurred speech, jerky uncoordinated movement, unsteady walk, stumbling, dropping things, etc.
A person with a hidden gene for a particular disease is commonly called a carrier. This person carries a gene for a disease, however, the disease may not always attack the person's body.
A carrier of a genetic disorder who does not show symptoms is most likely to be heterozygous for the trait and able to transmit it to his offspring. The term heterozygous refers to a pair of gene with one dominant trait and one recessive trait.
In order to have a child with cystic fibrosis, both parents must be carriers (assuming neither of the parents actually have CF; then obviously they will have symptoms). In CF, a carrier has no symptoms, unlike sickle cell anemia, where a carrier will have mild symptoms of the disease. A carrier of CF has only one defected 7th chromosome, and the other unaffected one makes the CFTR gene work correctly. When both are defected, the result is the CF disease, and normal CFTR genes are impossible to make, causing the person to have the disease.
a person who maybe carring the baby
A person who harbors a disease is called a carrier. Often, disease do not manifest in the carrier - they manifest in the descendants of the carriers.
Asymptomatic-- Persons who carry a disease and are usually capable of transmitting the disease but who do not exhibit symptoms of the disease are said to be asymptomatic.
Yes, they do in fact have to have mono in order to pass it on to others. That does not mean however, that they have to have symptoms of mono. A person can be a carrier, meaning that they have no signs or symptoms of a disease but are carrying it and can transmit it to others.
A carrier is someone who is able to transmit the disorder to someone else without being affected by it themselves. An example of this is hemophilia where the mother can carry the disease but she can only give it to some of her sons.
