Although the disease is caused by inheritance of a mutant gene, the symptoms usually don’t show up until between ages 30 and 50. The disease is characterized by slow but steady mental deterioration that begins with moodiness and ends fatally with severe mental illness. One tragedy is that carriers of the fatal gene often don’t know their condition before having children of their own. Children whose parents are known carriers grow up haunted by the 50% probability that they, too, carry the gene.
Late last year, however, a team of scientists from several institutions reported making a breakthrough that will lead to a test for the Huntington’s disease gene. With the aid of experimental genetic probes, James F. Gusella, a doctor at Massachusetts General Hospital, and his colleagues studied the genes of 135 members of a large family in Venezuela that is plagued by Huntington’s disease. While the team didn’t find the gene itself, they did discover an unusual genetic variation that seems to accompany the mysterious gene when it is passed along. Hence, it might serve as a “marker” for the Huntington disease gene.
