reproductive system
• 5-fold increased in aberrant elongating spermatid heads
• spermatids exhibit an increase in di-methylation of histone H3 Lys4 compared with control cells
• at 4 and 19 weeks
• reduced XY synapsis in spermatocytes
• at 4 and 19 weeks
• to a greater degree when heterozygotes are mated

growth/size/body
• at 4 weeks but not 19 weeks

cellular
• 5-fold increased in aberrant elongating spermatid heads
• spermatids exhibit an increase in di-methylation of histone H3 Lys4 compared with control cells
• spermatocytes exhibit persistent double-strand DNA breaks in meiotic prophase unlike in control cells

homeostasis/metabolism
• spermatocytes exhibit persistent double-strand DNA breaks in meiotic prophase unlike in control cells

endocrine/exocrine glands
• at 4 and 19 weeks
