Acp2tm1Psa/Acp2tm1Psa mice develop lower thoracic kyphosis and upper thoracic lordosis with age

behavior/neurological
N
• at 3 months, no defects observed in an open field test, a rotarod test, a hanging wire test or a hot plate test
• in mice greater than 8 weeks of age, about 7% had generalized, tonic-clonic seizure

skeleton
• reduction in the size of the intervertebral foramina
• lower thoracic kyphosis is first observed at 6 months of age
• after 6 months of age, kyphoscoliotic malformations of lower thoracic and lumbar vertebral column
• upper thoracic lordosis is first observed at 6 months of age
• vertebral arches have stunted pediculi that extend over almost the entire length of the vertebral bodies at 15 months of age
• at 15 months of age, vertebral bodies are thickened along their dorsoventral axis and show a reduced craniocaudal height
• reduction in calcium salts within compact bone
• regions of cancellous bone, most notably within vertebral bodies, show an abnormally coarse and locally hyperdense meshwork of mostly longitudinally oriented trabeculations
• decreased mineralization, beginning at 6 months of age and progressive

nervous system
• in mice greater than 8 weeks of age, about 7% had generalized, tonic-clonic seizure
• microglial morphology shows a change toward an epithelioid morphology at later ages
• localized astrogliosis in those regions showing increased lamp-1 staining

cellular
• lysosomal storage is observed in the kidney (podocytes and distinct segments of the nephron) and in the brain (astroglia, cerebellar Bergmann glia, ependymal cells, and microglial cells)
• enlarged lysosomes in some podocytes and portions of Henle's loop that are located within the inner stripe of the outer medulla

renal/urinary system
• enlarged lysosomes in some podocytes and portions of Henle's loop that are located within the inner stripe of the outer medulla

hematopoietic system
• microglial morphology shows a change toward an epithelioid morphology at later ages

immune system
• microglial morphology shows a change toward an epithelioid morphology at later ages
