This links to a story in the Globe & Mail about research for Huntington’s disease. That’s a degenerative neural disease that strikes people in their forties, after they have had children–and it’s inherited as a simple dominant, so 50% of the children are likely to have to too. It affects both body and mind, sometimes causing rages or irrational behavior. Now, there’s a promising lead: an enzyme snips Huntington’s abnormal protein into toxic segments, so if we can block the enzyme, we can slow the progress of the disease. One of its most intense researchers has the gene himself. Read the article, then the comments; they are most insightful.
