WebHuntington's disease (HD), a neurodegenerative disorder characterized by loss of striatal neurons, is caused by an expansion of a polyglutamine tract in the HD protein huntingtin. This gene encodes a protein belonging to a class of huntingtin interacting proteins characterized by WW motifs. WebAutosomal recessive is a pattern of inheritance. If a parent has an autosomal recessive trait, they'll show no symptoms. In order to pass it on to their children, both parents need to carry the trait.

Web29 mrt. 2024 · Huntingtin is a disease gene linked to Huntington's disease, a neurodegenerative disorder characterized by loss of striatal neurons. This is thought to be caused by an expanded, unstable trinucleotide repeat in the huntingtin gene, which translates as a polyglutamine repeat in the protein product. WebHuntington's (or Huntington) disease (HD) is genetic, and inherited in an autosomal dominant manner. This means the gene that causes it, called HTT , is one that both males and females have. Therefore, HD can affect males and females, and can be inherited from a mother or a father.

Web4 mrt. 2024 · Huntington's Disease is an example of dominance. In a dominant trait, it is the capital letter B that is the mutated (bad) copy of the gene, so only one mutated copy of the gene will result in disease.
