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.
