On the short leg of chromosome 4, in the HTT gene, there is normally a sequence of repeating bases like so: CAGCAGCAG... The CAG codon repeats 10-35 times in a normal person, however a person with HD will have 36-120 repeats of this codon.
Autosomal Dominant
HD is a genetic disease, and currently cannot be prevented.
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.
Huntingtons
An autosomal genetic disorder is Huntington's disease.
Im not sure about cured but we know the genes that cause some genetic diseases such as huntingtons
by inherited disorder from both or one parent, such as diabetes, cystic fibrosis, parkinsons disease, huntingtons disease etc.
Genetic testing can determine this (which is more involved than just a simple blood test).
Hungtington's disease is a dominant mutation in the gene that codes for the protein 'Huntington' It only affects a single gene, the remainder of the chromosome is unaffected and therefore it is not a chromosomal abnormality
By genetic testing. This involves laboratory testing on a small blood sample. It will normally be accompanied by family history tracking, and a physical examination, along with counseling.
The symptoms of Huntingtons Disease are, mental deterioration and uncontrollable movements; symptoms usually appear in middle ages.
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.
