Abstract
Huntington disease is a classic example of an autosomal dominant trait. Over the years a number of investigators reported anomalies regarding the age of onset of the disease that are inconsistent with this paradigm. Two models are proposed in which a maternal factor, cytoplasmic in 1 case, autosomal or X-linked in the other, acts to delay onset in a manner consistent with the previously reported anomalies. Relevant data from the Huntington''s Disease Research Roster are presented that reinforce and extend the previous observations.
