reproductive system phenotype ( J:183982 )
N
• female fertility is normal
abnormal male meiosis ( J:183982 )
• slightly lower median foci numbers of RAD51, DMC1, and RPA in spermatocytes indicating a potential role in double strand break formation or repair
• incomplete and spatially limited sex body formation and an increase in the frequency of sex chromosome pairing defects
• expression analysis indicates a failure of meiotic sex chromosome inactivation
abnormal male germ cell apoptosis ( J:183982 )
• spermatocytes undergo apoptosis at a stage equivalent to mid-pachytene by the end of the epithelial cycle stage IV of testis tubules
arrest of spermatogenesis ( J:183982 )
• stage IV arrest
