cellular
• this disruption in the synthesis of chondroitin sulfate glycosaminoglycans is evident in retinal interphotoreceptor matrix and hippocampus

immune system
• significant reduction in neutrophils in the bone marrow but not the spleen
• diminished numbers of macrophages in the bone marrow and spleen
• increased transitioning and activated microglia in the retinal outer plexiform layer and outer nuclear layer at 4 weeks and retinal outer nuclear layer and retinal pigment epithelium at 8 weeks of age, and in the hippocampus CA1, CA2, and CA3 at 4 weeks, 8 weeks and 1.5 years of age
• CD45+ inflammatory cells are found

hematopoietic system
• significant reduction in neutrophils in the bone marrow but not the spleen
• diminished numbers of macrophages in the bone marrow and spleen
• increased transitioning and activated microglia in the retinal outer plexiform layer and outer nuclear layer at 4 weeks and retinal outer nuclear layer and retinal pigment epithelium at 8 weeks of age, and in the hippocampus CA1, CA2, and CA3 at 4 weeks, 8 weeks and 1.5 years of age

behavior/neurological
• develops in older mice

nervous system
• increased transitioning and activated microglia in the retinal outer plexiform layer and outer nuclear layer at 4 weeks and retinal outer nuclear layer and retinal pigment epithelium at 8 weeks of age, and in the hippocampus CA1, CA2, and CA3 at 4 weeks, 8 weeks and 1.5 years of age
• rhodopsin staining shows disrupted outer segment morphology with disorganized and undefined columnar and tip structures
• at 1.5 years of age an increasing number of empty spaces are found surrounding cells in the CA1, CA2, and CA3 and a loss of wolframin ER transmembrane glycoprotein stained cells

limbs/digits/tail

growth/size/body

vision/eye
• rhodopsin staining shows disrupted outer segment morphology with disorganized and undefined columnar and tip structures
• absent chondroitin sulfate proteoglycans, ectopic synaptic interactions between photoreceptor and bipolar cells, increased apoptosis and progressive photoreceptor cell degeneration
• scotopic ERG at 8 weeks of age shows decreased a and b wave amplitudes

mortality/aging
• average lifespan of homozygotes is 20 months instead of 27 months

integument
• found in older mice

renal/urinary system
• CD45+ inflammatory cells are found
