| Homozygotes mice for disruption of exon 5 of the Htt gene (Hdhex5) die before embryonic day 8.5, initiate gastrulation, but do not proceed to the formation of somites or to organogenesis. Mice heterozygous for the Hdhex5 mutation display increased motor activity and cognitive deficits with significant neuronal loss in the subthalamic nucleus  | |
adult mice with a precise deletion of the short CAG triplet repeat encoding 7Q in the mouse HD gene commit more errors initially in the Barnes circular maze learning and memory test ( |
