Web11 apr. 2024 · Huntington’s disease is caused by excessive repeats of a portion of DNA, called CAG triplets, within the HTT gene, which provides instructions for making the huntingtin protein. This specific genetic defect results in the production of an abnormally long huntingtin protein, which is thought to be toxic and drive disease progression. WebHuntington disease (HD) is caused by the expansion of an apparently simple polyglutamine-encoding CAG repeat in the HTT gene. The more CAG repeats a person inherits the earlier the disease onset – simple. However, it has become apparent that the HTT polyglutamine encoding repeat is not actually so simple at the sequence level. can nifedipine cause weight gain
