N normal phenotype
behavior/neurological
• young adult mice exhibit a longer latency to find the target hole in the training phases of day 2 in the Barnes Maze
• young adult mice exhibit reduced spontaneous alternation in the Y-maze

reproductive system
• half of the epididymal lumens have decreased amount of sperm or are almost empty
• sperm exhibit abnormalities such as coiled/winding flagella, irregular shapes, and missing head
• some sperm show coiled/winding flagella
• some sperm exhibit missing heads
• sperm are less motile
• dramatic increase in cell death in testes
• R-loop and DNA damage levels are much higher and the levels of ciR-loop are increased in the testes
• about half of males are infertile

nervous system
• decrease in neuron numbers in the hippocampus
• decrease in neuron numbers in the hippocampus
• increase in DNA damage in the hippocampus
• increase of circRNA:DNA formation (ciR-loop) levels in the hippocampus
• overall RNA:DNA (R-loop) levels are increased in the hippocampus

endocrine/exocrine glands
• dramatic increase in cell death in testes
• R-loop and DNA damage levels are much higher and the levels of ciR-loop are increased in the testes
