There are three groups of symptoms: For details on symptoms, please visit the Symptoms page. HD is caused by a defective gene on chromosome 4 that causes an excessive build-up of the Huntingtin protein. Genes come in pairs — one from each biological parent — and they form the basis of everything from height to eye colour to genetic health.
The affected chromosome is not gender-specific, so both genders have equal risk of inheriting the faulty gene.
This means it cannot be caught, as it is not an infection, and it can only be passed on at the point of conception. If you are not born with the faulty gene, you will never develop HD. HD cannot skip a generation either. The only way to inherit the disease is for it to pass directly from biological parent to child.
Genetic Factors HD is acquired genetically. This means that you are only at risk of developing the disease if one or both of your parents also has the disease. The faulty gene can only be passed on at point of conception.
Every person with an HD-positive parent has a 1-in-2 chance of inheriting the faulty gene that causes HD. If your parent is at risk of or has the disease, then you and your children are also considered at risk of inheriting the faulty gene which causes the disease.
Some people diagnosed with HD may not be aware that they have a family history of the disease. Historically, HD was misdiagnosed as a number of other conditions, so many families were unaware of their genetic risk. In other cases, the person carrying the faulty gene may have passed away from other causes of an unrelated condition or in an accident before symptoms appeared, so the family is unaware of the possibility of the genetic disease.
The decision to have children can be difficult if you or your partner are at risk for HD. Some people conceive naturally, some adopt, some seek IVF treatment and some choose not to have children.Huntington's disease was the first disease for which predictive testing was offered.
