WebMutations in the HTT gene cause Huntington's (or Huntington) disease and juvenile HD. The HTT gene provides instructions for making a protein called huntingtin. Although the function of this protein is unknown, it appears to play an important role in nerve cells (neurons) in the brain. When the huntingtin protein is abnormally made, it can lead ... WebSince this gene codes for the huntingtin protein, the mutant form of the gene creates an altered form of the huntingtin protein, thus resulting in degeneration of the involved nerve cell and, in turn, the onset of the symptoms of HD. (For more information about HD symptoms, click here .)

WebMutations in the HTT gene affect the number of repeated sequences. There is a range of values that indicate HD status. A repeat value of 26 or less is considered normal. Values … WebCommon types of mutations include substitution (a different nucleotide is substituted), insertion (the addition of a new nucleotide), and deletion (the loss of a nucleotide). These changes within DNA are called point mutations because only one nucleotide is substituted, added, or deleted (Figure 17.5. 1 ).
Web17 sep. 2003 · Huntington's Disease (HD) is an autosomal dominant neurodegenerative condition with devastating consequences. HD is caused by the expansion of a CAG trinucleotide repeat stretch in the coding sequence of the HD gene that gives rise to a long polyglutamine tract in the huntingtin protein.
