| Mice homozygous for the recessive Htra2mnd2 mutation have a basal ganglia disorder initially described as an early onset motor neuron disease. This is first outwardly evident by 21 to 24 days of age as an unsteady gait with extended hind limbs, repetitive movements and episodes of sudden arrests. This progresses to include severe muscle atrophy, hunched posture, increased imbalance, chorea, dystonia, and progressive akinesis. A failure to gain weight becomes evident shortly after the onset of the other symptoms and by 35 days of age wildtype littermates are twice as heavy as the mutants. Body fat is not detectable at necropsy. Both the spleen and the thymus drop from normal weights at 23 days of age to 10% of normal at 30 days of age and the thymic corticomedullary junction is lost. Death usually occurs within two weeks of disease onset, by 40 days of age. The growth retardation is not the primary cause since disease is not delayed by intragastric feeding.
