Huntington's disease has autosomal dominant inheritance, meaning that an affected individual typically inherits one copy of the gene with an expanded trinucleotide repeat (the mutant allele) from an affected parent. [26] Since the penetrance of the mutation is very high, those who have a mutated copy of the gene will have the disease.
However, in individuals affected by Huntington's disease (an autosomal dominant genetic disorder), the polymorphic locus contains more than 36 glutamine residues (highest reported repeat length is about 250). [7] Its commonly used name is derived from this disease; previously, the IT15 label was commonly used.
Huntington's disease, which affects about 30,000 Americans, is a fatal, inherited disorder that causes progressive movement, psychological and cognitive problems. If a parent has it, their ...
These often are translated into polyglutamine-containing proteins that form inclusions and are toxic to neuronal cells. Examples of the disorders caused by this mechanism include Huntington's disease and Huntington disease-like 2, spinal-bulbar muscular atrophy, dentatorubral-pallidoluysian atrophy, and spinocerebellar ataxia 1–3, 6–8, and 17.
Huntington's disease (HD) is a rare autosomal dominant neurodegenerative disorder caused by mutations in the huntingtin gene (HTT). HD is characterized by loss of medium spiny neurons and astrogliosis. [30] [31] [32] The first brain region to be substantially affected is the striatum, followed by degeneration of the frontal and temporal ...
This is the case for Huntington's disease, where the trinucleotide repeat encodes a long stretch of glutamine residues. When the repeat is present in an untranslated region, it could affect the expression of the gene in which the repeat is found (ex. fragile X) or many genes through a dominant negative effect (ex. myotonic dystrophy). [citation ...
