Compare the inheritance of Huntingtons disease with the inheritance of sickle cell anemia?
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.
How can you inherit huntingtons disease?
Huntington's is a genetic disease meaning that it is inherited to offspring of effected parents. If one of your biological parents have it you are at risk. I would ask my doctor for genetic testing to see if I had it.
Is Huntingtons disease a hereditary bleeding disorder passed from mother to child?
No. While it is a hereditary disease it is not at all a bleeding disorder, nor is it only passed by the mother. It is a degenerative, neuropsychiatric disease that can be passed by either the mother or father. If the parent has it, the child's chance of inheritance is of the faulty gene is 50%.
Why is huntingtons disease more common than other serious dominant genetic disorders?
Huntingtons is a genetically inherited disease from a parent. when chromosomes are passed onto a child, the child wont always receive the chromosome containing the gene. But, if they do inherit the gene they will have the disease no matter what, because the disease is dominant. If it was recessive, the child could inherit the disease but not necessarily get the disease.
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.
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.
A female who is a carrier of Fabry's disease has what chance of having a daughter who is a carrier?
The mother has a 50% chance of passing the defective recessive gene to her daughters who will be carries of the disorder (like their mother).
Why are sex-linked diseases more likely to affect sons of female carriers?
The son would automatically get the Y chromosome from the father. The son's X chromosome has to come from his mother. Females are XX, so he has a fifty-fifty chance of receiving the disease carrying gene. If he receives the disease carrying gene he will have the disease, if he doesn't then he will neither have the disease nor be a carrier. A daughter has to receive one X chromosome from her father and one from her mother. If the father doesn't have the disease, then the daughter cannot have it. If the mother is a carrier, then she has a fifty-fifty chance of being a carrier.
