mortality/aging
lethality, incomplete penetrance ( J:183398 )
• fewer than expected homozygotes are found, lethality occurs sometime before weaning

reproductive system
abnormal outer dense fiber morphology ( J:183398 )
• outer dense fibers are completely disorganized
abnormal sperm axoneme morphology ( J:183398 )
• axonemal microtubules are completely disorganized
absent sperm fibrous sheath ( J:183398 )
• the sperm principal piece appears to be missing the fibrous sheath
kinked sperm flagellum ( J:183398 )
• most (98%) sperm have a very short crooked tail
short sperm flagellum ( J:183398 )
• most (98%) sperm have a very short crooked tail
oligozoospermia ( J:183398 )
• sperm count in the epididymides is reduced to 8% that of wild-type controls
abnormal spermatid morphology ( J:183398 )
• elongated spermatids appear to lack flagella
decreased testis weight ( J:183398 )
• at 8 weeks of age
abnormal epididymis morphology ( J:183398 )
• mostly filled with cell debris and contain few sperm

respiratory system
abnormal respiratory motile cilium morphology ( J:183398 )
• tracheal motile cilia lack some outer dynein arms and contain only about 4 of them per cross section compared to 9 per cross section in wild-type controls
left pulmonary isomerism ( J:183398 )
• randomized left-right patterning with 6 of 22 mice showing left-sided isomerism
lung situs inversus ( J:183398 )
• randomized left-right patterning with 8 of 22 mice showing situs inversus

nervous system
hydrocephaly ( J:183398 )
• starting at P4

growth/size/body
left pulmonary isomerism ( J:183398 )
• randomized left-right patterning with 6 of 22 mice showing left-sided isomerism
lung situs inversus ( J:183398 )
• randomized left-right patterning with 8 of 22 mice showing situs inversus

endocrine/exocrine glands
decreased testis weight ( J:183398 )
• at 8 weeks of age
