normal phenotype
• male mice are viable, healthy and fertile, with no apparent physical or behavioral phenotype or signs of embryonic lethality; at 15 months of age, histological analysis shows no significant change in retinal ganglion cell (RGC) soma density at locations proximal, intermediate, and distal to the optic nerve head, while TEM indicates normal RGC axon abundance with no morphological defects in RGC axons or their surrounding myelin sheaths, suggesting absence of RGC degeneration and axonopathy under normal physiological conditions
